We had 13 people (6 adults, 2 teens and 5 children) staying in the flats. Although there was no larger sitting area, we could sit the 6 adults comfortably in one room. The location was fantastic for some great restaurants, the metro and a number of shops for groceries. The Vatican was a short walk and there river was an excellent spot to run/walk along. Dealing with the people who own the flats was very easy. They were quick to get in touch with us over email to provide information, but also wonderful once we got there by giving us great tourist ideas, providing extra towels, bedding and coming by to clean. We thoroughly enjoyed our stay here.
