This for me is 4.5 stars. The apartment is very stylish and in a convenient, yet quiet location in Trastevere. The apartment is light and bright and the outside space is lovely. There is lots of storage space and for two adults the apartment was very spacious. You can walk to all the major sites in no more than 40 minutes (Colosseum 40 minutes, Pantheon around 10 minutes). Mauro is a really lovely host, he was always quick to reply, gave us lots of information, arranged a taxi to the airport on our way home and was there at check-in and check-out to help us with our luggage.
