Valerio is always there for you, he is quick and accurate in his responses. We did not have to wait a second outside the flat when we arrived, which is highly appreciated (specially when you arrive at night and happens to be raining). The flat has a special charm, it is very comfortable and clean. The location is fantastic, just a 10 minutes walk from the Colosseum and a zone full of restaurants and cafeterias. Definitely a safe investment for your holidays.
