Carmine's apartment is great!
Location is very central in the Trastevere area, which is much less touristy than the central part of Rome.
Communication went very well, quick to reply and everything was organised well. His friend Christian was there when we arrived to let us in and show us around. He also gave great tips for restaurants and wine bars in the area.
The apartment itself is very cosy and clean, exactly like the pictures. It doesn't have any windows, but the aircon and aerator works very well to keep the apartment nice and fresh!

All in all a very pleasant stay, and we can highly recommend it!
