Antonio & Valentina's place is very confortable and near of every main attraction. We didn't have to use public transport for anything, everything was reacheable enough to get on foot (even Vatican City and Rome's Olympic Stadium!) . I would recommend it to everyone.
Antonio is such a great guy, he helped us with the bags and sent us tips and recommendations for everything, like food, drinks, attractions, etc.
We really enjoyed our stay, Rome is an amazing city and the appartment is in the heart of it, only a few steps from Trevi Fountain.
