Alessandro was very responsive, and the location is really awesome, but there were issues with cigarette smoking, noise, and cleanliness.
The unit is part of a single apartment that's divided into five units. Smoking is allowed in some of the other units. The smell of smoke lingered in the hallways and staircase inside the apartment, and it got into my room as well. In addition, the walls were very thin, and I could hear anything that was going on in the other four units. On the second night I spent there, one of the rooms got really loud. None of this was mentioned in the listing when I booked it.
Lastly, the unit was just not very clean. The window was dusty, as was the AC controller, there was hair in the shower, and the floor wasn't clean either.
When I communicated these issues to the host, he sent housekeeping to clean the room (which I really appreciated), but he did not help with the noise or the smoke.
