A very nice, small place, perfect for two persons, located central in Rome in a quiet neighbourhood.
Very close to a supermarket to buy breakfast and snacks from (and more of course).
Walkingdistance from central station, so we took the train from airport instead of taxi.
You also have walking distance to all the nice places in Rome if you want. Taxi from station to Vatican was only 10 euro (we where short of time to get there).
I can really recommend a stay at Massimos place.
