We unfortunately only had one night at Marco's place but we loved it! He was very accommodating with a last-minute change to our check in schedule and the apartment was perfect for us four adults coming off a two week trip and about to fly out of Rome.
The apartment was very clean, comfortable, and so close to the Colosseum you have a view of part of it from one of the bedrooms, which was gorgeous at night when it was lit up. If we are ever back in Rome we would love to have more time here!
