The whole experience was really excellent:
1. Nicoletta was very responsive to our messages
2. We had a great check-in experience even though it was late at night
3. The location is PERFECT for sightseeing in Rome - right next to the Vatican, and also right next to the subway!
4. Great apartment - lots of space (there were 4 of us), everything that we needed in the kitchen and bathrooms, not a lot of noise from the street.

Overall I would recommend this to anyone!
