The best part of this accommodation is location- walkable, close to colosseum, public transport nearby, good places to eat:)
The main thing we were really disappointed and would not recommend this place during winter period is because of heating system. We tried to communicate with the host (also with airbnb support) followed all the instructions he mentioned, but still one AC for such an apartment with high ceiling is definitely not enough. We even left AC on for all day long and still was not comfortable to be inside without multiple layers of jackets.
The building itself is beautiful, as mentioned location is very attractive, but the apartment inside needs refreshment (or at least new replacement of furniture)
Good luck, Patrizio , and really hope you will take into account my comments.:)
