I stayed at Carmen's place with my parents and my brother. We arrived much later than we expected due to flight delays, but we kept in touch with Carmen and she was very accommodating to our situation. When we finally did arrive, she gave us a detailed tour of the apartment and gave us plenty of local tips. The apartment was clean and looks really nice (including both full bathrooms). Also, the location is perfect - it's literally steps away from plenty of great restaurants, and within walking distance to all the great sites of Rome. Overall, I would highly recommend this apartment.
