Great apartment. Centrally located near to the colosseum. Was in a lovely, traditional Roman building. Apartment was big and clean and the communication with the hosts was great.
Only small thing to note is that it is above a restaurant with pavement dining so light sleepers might find it difficult to get to sleep as the chatting does go on until around midnight. It didn't disturb us too much as we were also out late most nights but it is worth knowing this.
