The room is very clean, recently renovated and tastefully decorated. It consists of a room and bathroom and has the feel of a room in a boutique hotel. In fact the B&B is run like a hotel and cleaning services are provided every day in addition to breakfast every morning around 9:00am. The breakfast generally consisted of a croissant, toast, jam, butter, juice, Nespresso coffee and sometimes Nutella.
They were quick to reply to any questions and were very helpful in setting up checkin details etc. However being a small operation they do have their constraints; for example they had to ask us the night before to check out a little earlier than planned.
The location is reasonably convenient. Very close to Basilica di Santa Maria Maggiore, and the Coliseum. It is about half an hour walk to the historic centre if you don't mind navigating Roman hills. It is very close to the metro as well, and you can take the same line to Vatican without connections.
Overall we had a very good stay and highly recommend this place.
