Great location, comfortable bed (larger than a queen sized bed, not quite North American king sized), very responsive and helpful host. Kitchen has everything you need. Appreciated the washing machine and drying rack. As other reviews state the shower is small, but very functional. Note It is on the third floor with no elevator.
The location is fabulous - walk to almost every major sight in Rome, carrefour express grocery less than 200 meters, and many restaurants nearby.
Quiet at night.
