The place where I have been liveding during the quareantine.

I'm Mexican,. I had lived in the same place for a long of time, but now I have been liveding in Spain sincefor six months ago.

By "in the same place", do you mean in Mexico?

The word "since" in English doesn't exactly correspond to "desde" in Spanish. "Since" is a word that you use to refer to periods of time, or as a subordinating conjunction equivalent to "because".

In the living room, there areis a couch, a TV, a table and sinx chairs,. I spend a lot of time here because it's the place of the apartment with more light and spacebrightest and biggest room in the apartment.

When you have two independent clauses, they usually need to be separated by one of the following: (1) A period, (2) a comma and a coordinating conjunction, (3), a semicolon.

This is why I replaced the comma after "chairs" with a period.

My appartment is ion the first floor of a building, this. It has five floors, but it's not too big, t. There are only two apartments ion everyoneach floor.

"Everyone" written as one word can only refer to people, not things.

There areis a bakery next to the building and a little supermarket ion the other side.

The place where I lived is actually very nice and quiet, even It has. There are a lot of stores ion my street .

Is it "lived" (past tense), or are you currently living there?

After almost three difficult months, people here in Spain started to come back to the streets.

The simple past "started" indicates that you're telling a story about something that happened in the somewhat distant past that is not really connected to your current life (for example, because you don't live there anymore). If it's something that's happened recently and that is related to your present experiences, you would use the present perfect: "people here in Spain have started to come back to the streets."
