We didn’t eat anything  and we didn’tor go to bathroom either on the whole way in airplane.

According to Taiwanese policy travelers  should be self-isolated from public, living in a place, not allowed to go outinside, for  14 days and  sh. We could only take a taxi from Taoyuan airport to ourhe apartment we were staying in, which iwas my friend spare apartment where no one live's.

It was very safe on the way from Jakarta airport to Taiwan because when we were in the airplane, no one sat in front of us, four people sat ton our left across four columnfour rows and two aisles from us,away, the window was on our right , and only one iIndonesian sat one row behind us.

I'm not 100% sure what you intended to indicate with regards to the location of the four people.

We didn’t eat anything  and we didn’t, nor did we go to the bathroom either onduring the whole way in airplanetrip.

By the time we arrived Taiwan I felt very happy,. I thought, "fFinally we camare back to our home."

It’ was already 10 pm in Taiwan and there were peopleabout as many as the people as in jJakarta airport, which meant fewin other words not very many people.

According to Taiwanese policy, travelers  should be isolated from public, living in a place, not allowed to go outside, for  14 days and  should only take a taxi from Taoyuan airport to our apartment, which is my friend spare apartment where no one livesquarantined for 14 days, without being allowed to go outside. We could only take a taxi from Taoyuan airport to the place we're staying, an empty apartment belonging to my friend.

We headed for the taxi receptionstand.

The receptionist letmade us fill theout a form while  two taxi drivers sprayed alcohol  over our luggage and put them into  the compartment of taxibefore putting it in the trunk.

The taxi driver also sprayed  alcohol all over our bodyies.

The taxi meter was running, showing the fare that we would have paid pandemic if it weren't for the pandemic, which stoppedstopping finally at 2300 TWD in the end.

The taxi driver told us that we only needed to pay 1044 TWD, and that the Taiwanese government would play the rest of it.

It took us 2 hours including the time that our driver wasgot lost on the way to our apartment.

We took all the luggage up to the fifth floor, picked out all the clothes we needed before taking a shower, and we went to the bed at 1 am.

It was very safe on the way from Jakarta airport to Taiwan because when we were ion the airplane, no one sat in front of us, four people sat on our left across four columns and two aisles from us, the window was on our right , and only one iIndonesian sat one row behind us.

"on the plane" or "on the bus" are phrases in English that you will hear often.

"the window" to specify the exact window to your right.

We didn’t eat anything  and we didn’t go to the bathroom either onduring the whole way inon the airplane.

"the" again is used to be specific that "the bathroom" refers to the bathroom inside the airplane.

"during" is a better preposition to describe the ongoing amount of time that passed on the flight.

By the time we arrived to Taiwan I felt very happy,. I thought, "finally we came back to our home."

"to" or "from" are used to describe your destination.

It’ was already 10 pm in Taiwan and there were people as many as the people as in jJakarta's airport, which meant few people.

"was" is needed since the rest of the sentence is past tense.

"Jakarta" Proper nouns are always capitalized.

"as many as" this is a phrase used for comparison. "as many people as" because you are comparing the amount of people between Taiwan and Jakarta.

According to Taiwan's policy, travelers  should be isolated from public, living in a place, not allowed to go outside, for  14 days and  should only take a taxi from Taoyuan airport to our apartment, which is my friend spare apartment where no one lives.

This paragraph is a bit confusing, because you are stating Taiwan's general travel policy. However, it then switches to taking a taxi from from the airport to your apartment and talks about your friend. I'm not sure what you mean.

The receptionist lethad us fill theout a form while  two taxi drivers sprayed alcohol  over our luggage and put them into  thea compartment ofin the taxi.

"had" is more appropriate, because "let" implies permission had to be given.

"two taxi drivers" there is more than one, so you need an "s" for plural.

"a compartment" because it means it is a space in general, though I'm not sure if you meant the trunk?

The taxi driver also sprayed  alcohol all over our body.ies.¶

"the taxi driver", because we are being specific that it was that taxi driver who sprayed you.

"our bodies" because "our" is a plural possessive pronoun, so body becomes plural.

The taxi meter was running showing the fare that we would have paid pandemic if it weI'm not sure what you mean here. Do you mean they gave you two fares, one showing the curren't forare during the pandemic, which stopped at 2300 TWD in the end. and one showing you a pre-pandemic fare?

The taxi driver told us that we only needed to pay 1044 TWD, because the Taiwan government would play the rest of it.

"because" is used to explain why you needed to only pay 1044 TWD.

"the Taiwan government" because we are being specific as to which government.

It took us 2 hours including the time that our driver was lost while driving to our apartment.

We took all the luggage up to the fifth floor, and picked out all the clothes we needed forto takinge a shower, and w. We went to the bed at 1 am.

"the fifth floor" again, we are being specific that it is that fifth floor on that specific building.

I started a new sentence for when you went to bed, because it sounds like you took a shower first then went to bed.

Finally, we got to Taiwan

It was very safe on the way from Jakartathe airport in Jakarta to Taiwan because when we were in the airplane, we weren't close to anyone: no one sat in front of us,; there were four people sat on our left across four column, but they sat four seats and two aisles from us,; the window was on our right ,; and only one iIndonesian sat onin the row behind us.

"The Jakarta airport" is fine, but this sounds better to me.

You've talked about how you weren't close to the other passengers, but it would be better if you explicitly said that it was safe because you weren't close to people.

"Column" sounds odd so I've replaced it with "seats," but I'm not sure if that's what you meant.

You might also want to separate the description of the seating into separate sentences, although this would also be acceptable.

We didn’t eat anything  and we didn’t gor go to tohe bathroom either onduring the whole way in airplaneflight.

By the time we arrived in Taiwan, I felt very happy, and I thought, "fFinally we came back to ourhave come back home.

"We came back [to our] home" is also fine, but "we have come back" makes more sense to me as you are describing what is happening in that moment.

It’ was already 10 pm in Taiwan and there were people as many as the people in jakarta airport, which meantre were in the airport in Jakarta, in other words, only a few people.

According to Taiwanese policy, travelers  should be isolated from the public, living for 14 days. They must stay in a one place, are not allowed to go outside, for  14 days and  shouldand can only take a taxi from Taoyuan airport to our apartment, which iswhere they are staying, in our case, my friend's spare apartment where no one lives.

We headed for the taxi receptionstand.

The receptionist let us fill thea form while  two taxi drivers sprayed alcohol  over our luggage and put them into  the storage compartment of the taxi.

You haven't explained what form it is, so it doesn't make sense to refer it as "the form."

The taxi driver also sprayed  alcohol all over our bodyies.

The taxi meter was running, showing the fare that we would have paid pandemic if it weren't for the pandemic, which stopped at 2300 TWD in the endended up being 2300 TWD.

Alternatives:
- "and it finally stopped at 2300 TWD."
- "which turned out to be 2300 TWD."

The taxi driver told us that we only needed to pay 1044 TWD, because the Taiwanese government would play the rest of it.

ItThe trip took us 2two hours, including the time thatduring which our driver wasgot lost on the way to our apartment.

"It took us two hours" is fine grammatically but sounds a bit ambiguous.

We took all the luggage up to the fifth floor, picked out all the clothes that we needed for taking shower, and we went to the bed at 1 am.

You've introduced a parallel structure that consists of "we" and a verb in the past tense ("We took… picked…"), so the last part needs to follow that
