Translation of creíble

In this email I would like to tell you what occured to me in Italy during the summer vacation last year. So, I went to Italy for four days. First I stayed in Firenze, than I decided to go to Rome.
The ride took us through mountainous areas, covered with dark green forest, with so many curves that I got sick. I wanted to vomit but I held myself back, as there were so many other next to me.
The same evening we left Patagonia and flew to the capital of Argentina, Buenos Aires. We have waited a long time for this moment as we have not been in a city for almost two weeks and we usually love the city.
