It was the worst stay imaginable. Upon arrival, the room felt hot, and the old air conditioning unit wasn't cooling; the temperature was over 40°C (100°F). We contacted the relevant department, and they said they would send someone. We waited until 7:30 p.m. (having arrived at 3:00 p.m.), but after such a long wait, we went out to eat. When we returned at 9:00 p.m., the room was still hot—above 30°C (84°F)—even though it was night and the weather outside was cool. We called the person in charge again; they claimed someone had already checked it and reported that the unit was working, but that nothing could be done at that hour. We were told we had to spend the night as it was and see who could be sent to check it again the next day. We tried to cancel and request a refund, but were told no; they could only deal with the matter the following day, as there was nothing to be done at that moment. Consequently, we had to endure the heat; my children were uncomfortable and slept without clothes due to the intense heat. The next morning, we woke up hot again, and the apartment had no running water; we couldn't bathe or use the toilet. As a result, we left the apartment before completing our reservation and requested a refund.
