We were staying in Rome for 3 nights but felt right at home with the charming hostess and the small, but comfortable interior. It was never crowded or dirty - meeting other guests was a welcome experience.
A great local food place is the Trattoria Etruria where we had a very nice Cacio e Pepe. Or the more modern SalSamente across the street - a bit more expensive, but very kind, thoughtful service and a delicious Amatriciana.
Our time in Rome was too short - when we come back we will definitely stay at Cristina's again. The beautiful house has a lift, too.
