Nevertheless the worst was on that night, we were exhausted by the jet lag and went to sleep, all of a sudden at 3am an alarm went off, at first I thought it was my wife clock alarm, but each time increased, therefore I got up and opened the door. Oh my God!! straing away I noticed a strong smell of fire and a lot of smoke. The hotel was on fire, it was burning. I couldn't believe it! I thought it was a nightmare. my wife jumped of the bed and without though, we dressed and took the passport and money. this was a mistake that could have gone baldy wrong.
Take the lift - said my wife.
Are you crazy? we must use the stairs down - I reply.

Nevertheless the worst was on that night.  We were exhausted by the jet lag and went to sleep.  All of a sudden at 3am an alarm went off, and at first I thought it was my wife’s clock alarm; but as the time increased, I got up and opened the door. Oh my God!!  Straightaway I noticed a strong smell of fire and a lot of smoke. The hotel was on fire, and it was burning. I couldn't believe it! I had thought it was a nightmare. My wife jumped of the bed and without thought, we dressed and took the passports and money.  This was a mistake that could have gone baldy wrong.
“Take the lift”, said my wife.
“Are you crazy? We must use the stairs to go down,” I replied.
We were on the sixth floor and the fire was on the fourth.  Despite having plenty of smoke in the stairs (or ‘stairwell’),  we were able to go down with hardly any danger.

@juanjolola Nevertheless, the worst had come that night. We were exhausted by the jet lag and fell asleep. All of a sudden, an alarm went off at 3am. At first I thought it was my wife's alarm clock, but as more time passed, I decided to get up and open the door. "Oh my god!" I gasped in horror. There was a strong smell of something burning, fire. Before I knew it, there was smoke spreading everywhere around the hotel corridors. That's when it got to me, the hotel was on fire!! The building was burning!! I couldn't believe it! I thought it was a nightmare. My wife noticed something awry(something wrong) and jumped out of bed. Without a thought, we got dressed, took our passports and belongings before running out of the hotel room. This was a mistake that could have gone horribly wrong..."Take the Lift" my wife said. "Are you crazy? we must use the stairs to get down to the ground floor!" I replied almost in an instant. We were on the sixth while the fire was on the fourth. Despite having an enormous amount of smoke spreading throughout the stairwell, we were able to go down without much harm.

the most common error is run-on sentence(not putting fullstops) but it's okay! u can work on it!!
second error is the phrasing but that can be fixed eventually!!
overall it was written quite well!
