The room is cosy and clean. the Location is just great, almost all hightlights are within walkable distance.
Costanza was very nice and answered all our questions. She gave us a lot of recommendations where to eat and what to do in Rome.
Even if we did not see her much, she was really caring. We could text her at any time and she answers back. She even sent us her recommendations for restaurants via sms (we bought an italian simcard for our stay).
