At the beginning of the trip everything was nice. A good communication, etc.. However, when we arrived we realized that the air condition was not working properly. Therefore, we make contact with Brian and Olga. It took something like 3 days until someone came and checked it. It was recognized that the air condition has really some issue and something has to be changed. However, it seems that this was not happening in our stay. We had only one fan and it was nearly impossible for us to sleep until 2 in the night because of the heating inside the flat. I have to say that this was really not great since we had to work during the week. Therefore, the flat was nice but the circumstance where quite bad.
