I spent a weekend with my wife at Eugenio & Vanina's place. Although we were by ourselves we could have easily fitted with the kids. The location is great, in the heart of Trastevere overlooking nice restaurants and bars yet within walking distance of the major tourist attractions. Vanina was kind enough to meet us later than the stated check-in time and then allowed us to use the apartment after the check-out hours. She suggested a great location for a late dinner (challenging on a Friday night in Trastevere), instructions how to get to the appartment and was very responsive during the booking and throughout the whole visit. I would highly recommend the place!
