We had a very pleasant stay. We were greeted in an extremely friendly and courteous manner and Valentina was always available for questions. The room is part of a flat but has everything you need. A small balcony, a large bed, air conditioning and a private bathroom.
St Peter's Square is only a few minutes walk from the flat; from here most sights can be reached on foot. The flat is in a very quiet residential area.
As we mostly only stayed in the room for the night, it was perfectly adequate for our needs and we had a very nice few days in Rome.
