Good things first: the location is very nice, easily reachable, and in a quiet neighborhood. Paolo is very responsive and is trying to be helpful.
Still, if you want to have a relaxing stay, chose another listing.
This apartment is very old and poorly maintained: for me, every day there was a new issue. The heater was making so much noise I wasn't able to sleep the first night and had to switch it off for the following nights. Eventually, it also stopped heating and was just blowing cold air. There was no hot water in the shower, and the knob to regulate water temperature was actually broken and _glued_ back by Paolo, because he just couldn't fix it before my arrival (and I discovered it in the morning under the cold shower, because he did not bother to inform me about the problem when I arrived). Then he removed this knob altogether and regulated the temperature of the water so that it became boiling hot. The key was not opening the front door, I had to ask neighbors for help.
