We had a great stay in Rome in Roberto's apartment!
Its location is perfect, in the heart of Trastevere, so bars, cafés and restaurants are literally around the corner (e.g. the quite popular cocktail bar Freni e Frizioni), but the apartment is still quiet. But you'll also reach Campo di Fiori in 10 minutes walk. Vatican, Forum Romanum, Collosseum can also be reached by foot.
The apartment is clean and perfect for 2 people. The gallery where the bed and closet is located is really nice.
Roberto was really nice and provided us with a lot of information about the neighbourhood, restaurants and shopping.
I'd always come back to this apartment!
