The B&B is perfect if you want to relax after a long walk around Rome. The Room is very clean and nicely furnished, the atmosphere is nice and cosy and the owner can give important and useful information on where to go and what to do. He has got a great personality and is very helpful and kind. The breakfast is tipically italian (sweet) and very good.
The B&B is very close to two metro stops, so you can get there easily and it's very comfortable to explore the city from there. The street is quite busy and you can hear the traffic in the room, so if you like it very quiet, this is maybe not the right choice. But we never had problems sleeping as the bed is very comfortable.
