We booked a large, spacious room with private bathroom for three people, two months before a congress in Havana. We arrived around 11:30 pm as agreed. Our host informed us that due to renovations he could not stay with us but that he would accompany us to another house nearby and he did so. Upon arriving there the price would be doubled as we would have to stay in two rooms, which we did not want. The argument lasted for almost an hour. As it was already dawn and we were very tired from a long trip and difference of spindle, we decided to stay where we were and sleep there that night. The next morning our host returned the money we had paid to Homestay at the time of booking and showed us another house. We stayed in this house and the stay was great in Cuba, except for these first few hours. I point out that in Cuba the houses authorized to receive guests have a seal on their façade being blue when allowed to host foreigners. The two early houses did not have this seal, unlike the third, which kept the blue seal well visible.
