At first we were waiting for the host for 25 minutes, outside of the building and it was 0 degrees. Later when we entered in the flat inside was 15 degrees on the thermometer, so heating was probably turned on 1 hour before our entrance. Our co-host (Chiara) said to us that heating is set to 22 degrees but we later saw that it was set to 19. After we tuned on the aircondition, the power went out, so we had to go to the basement to turn it on again. The only good thing is that host (Simone) replied us immediately what should we do to enable it again.
Later when we went to sleep, we saw that badding is very dirty. Badsheet was full of various hairs (we have pictured it). Also we tried to clean it, but it was impossible.
