Great place to stay. Large bedroom with a fancy ceiling (see photos!), and the rest of a small-ish apartment but with everything we needed and more. We appreciated having a full apartment in the evenings while we visited the city of Rome during the day. Hosts were also very communicative and flexible when our travel plans changed a bit on our first day. Always nice to have check-in flexibility!
Note that the a/c unit is only into the bedroom (it couldn't handle the full flat), but this isn't a big deal. We just kept that door shut during the day so it would be cool at night for sleeping. Overall a fantastic place - will definitely look for availability if I return to Rome.
