I stayed at Andres's apartment on a business trip, and was unfortunately a bit disappointed by the apartment, although Andres was a very responsive host. In some cases, he was able to fix the problems with the apartment. In others, he wasn't.
The biggest issue is that the elevator opens right into the apartment. At first I thought that was weird, but I was ok with it because I was instructed on how to prevent the elevator from coming to my floor without my permission. However, several times during my stay, even when using the elevator lock as instructed, the elevator opened at my floor without my permission. It was a bit uncomfortable.
The two other issues were difficulties with hot water and window curtains that didn't cover the full window. A few times the boiler wasn't working, and even when it was finally fixed, I only had hot water for about 2 minutes before it turned tepid again. The curtain was just strange, as it only covered half of the window facing the street.
