"Overall very good but be careful with the noise"
If you are a light-sleeper the room might not be for you. The apartment is very good and characteristic. This unfortunately means poor soundproofing: you will hear most of what happens in the corridors and the rest of the apartment. The most disturbing is probably the bathroom right on the other side of the wall.
We didn't meet the owners but check in was smooth and on point. The room was clean and as described (maybe a bit smaller than expected). Great closet with code-lock and nice decor. Breakfast was really good with multiple options.
We chose the Trevi Fountain room because we knew we wouldn't stay much in the room. The room is small but comfortable and perfect for a lower budget. The position is great, very well connected with all the main touristic sites. Buses are the best. The neighbourhood is very quiet.
