Very clean and very confortable place.
We were 10 friends, and it was perfect for us, with 5 seperate bedrooms. The common room is quite small, but it doesn't matter much as you usually go to Roma to visit and spend some time outside.
The location is great, we walked to the busy part of Trastevere, and across the Tiber to the historical area. Even to the Coloseum, we walked.
