(I don't know how to say that, but it's the big ships) Airbnb was really amazing.

There was a shower, two bedrooms with TVs, a living room, a porthole and the air conditionning.

This can join the last sentence to avoid starting a sentence with 'but'!

There was a shower, two bedrooms with TVs, a living room, a porthole and the air conditionning.

The captain was driving the ship to Miami and when they arrived, Rayan slept in the boat while the man was going out.

'Going out' is correct but 'left' may be better.

However, he succeed to watch the movie 'Ratatouille'.

He watched it because after going to different Airbnbs, he went to Paris and he wanted to know what they could do.

I really appreciated this video and I hope you enjoyed reading my text.

One of the Ryan Trahan's concepts is to try all the Airbnb categories.

More naturally: One of Ryan Trahan's concepts is to try all the categories of Airbnb.

There are lots of categories but he wants to try literally all of them.

Or: "There are a lot of..."

In this video he just tried 4 categories.

"In this video" -> "In his most recent video" or "In one of his videos"
"this" is used to refer to something that was just mentioned, e.g., "Ryan Trahan recently posted a video called "I Tried Every Airbnb Category". In this video..."

"he just tried 4 categories" -> "he only tried 4 categories"
"just" in the above phrase means more like "just" in "it just happened", or "he just arrived". "only" might be a better fit.

But I think he will continue the series later.

This series will lasttake a lot of time ahah.

or "last for a long time"

In the video, he went to a ship Airbnb, a cabin, a big luxurious house and a house located in big farms.

"in big farms" -> "on a big farm" OR "a house located in big farms" -> "a farmhouse"

If he lived in each Airbnb for a while (like a day), it would be better to say "In the video, he stayed at..."

The ship Airbnb, the yalcht

There was a shower, two bedrooms with TVs, a living room, a porthole and the air conditionning.

The captain was drivingdrove the ship to Miami and when they arrived, Rayan slept in the boat while the man was going out.

If Ryan was sleeping when the man left the boat: "Ryan slept in the boat while the man went out"
If Ryan was sleeping in the boat during the time the man wasn't in the boat: "Ryan slept in the boat while the man was out"

It looked nice but the wifi wasn't good.

wifi could be written as Wi-Fi

However, he succemanaged to watch the movie Ratatouille.

I think when I will we older, I will love to have a house like this.

If you currently would love to have a house like this (but will only get it when you're older), then you would say "I would love to have a house like this when I'm older"
If you think that the future, older you would love to have a house like this: "I think that when I'm older, I would love to have a house like this"
Or something like that.

The fourth and the last was an Airbnb that was pretty simple but with a huge farm.

Better phrasing: "The fourth and the last Airbnb was pretty simple, but it had a huge farm." or "but it came with a huge farm"

He went to the farm and cut some flowers for his girlfriend in order to give her when they will see them in Paris.

-> "He went to the farm and cut some flowers to give his girlfriend when he sees her in Paris."

Of course, he was allowed to.

-> "Of course, he did this with (the owner's) permission."

To conclude, he passedspent two days in Paris with his girlfriend.

He booked a traditional appartment.

I didn't love it a lot because it looked like thea Royal suits ine from the 1900's.

We usually won't use "love" for this, we'd use "like".
I didn't really like it/I didn't like it much

Royal suits -> Royal suites? suits refers to the clothing, suites refers to a set of rooms.

Nevertheless, this appartment had a beautiful view overf Paris and the Eiffel Tower.
