The apartment is very central and it is easy to reach all parts of the historic center by foot. Mauro was friendly and professional, though obviously in a hurry. He hardly spent five minutes with us.
Be aware that the only window of the apartment is directly to a very noisy street - this was not clear to us from the description. With windows closed it was ok, but otherwise sleeping was difficult due to noise from cars, scooters and party people walking home. An issue for us was the cleanliness: there were little hairs in the bathroom and the floor had clearly not been wiped for quite some time. The floor mat and also the kitchen towel had apparently not been changed between the previous guests and us. Also, one of the pillows was unbearably uncomfortable, I went to the car in the middle of the night to get one of ours.
To sum it up, it would be more or less ok for a low-to-medium priced apartment. For the price we payed, and compared to other Airbnbs we've been to, we were a bit disappointed.
