There was a problem with the hot water and with the key to the entrance door. It didn't open the door. We waited at the street several times each day, until somebody left the building or opened the entrance door with a chip. The neighbors explained that we should have get a chip and not a key. The host didn't answer phone calls and messages for 2 days. When he answered, on the last day of staying in this flat, he offered to ring the neighbors' bells each time I want to enter the building. He refused to bring another key. I didn't get an answer about the problem with the water. We had freezing showers most of the times. It was a very short vacation so I couldn't spend time on looking for another flat so we stayed in this one, but it was very disappointing flat.
