Andrea's apartment is in a really nice, non-touristy neighbourhood full of restaurants, bars, and antique shops, while still being less than 10 minutes to the Duomo by metro.
When we booked, the photos showed different setups of the space, and we has assumed there were single beds AND a double bed. This isn't the case, as there is only a double bed and a couch now. Quite tight for 4 people, but we made it work!
Otherwise, everything was very clean and comfortable and we had a fantastic stay!
