This appartment really deserves 5 stars : very clean, good location (500 meters from a metro station and only 20 minutes walk from the Colosseum), aircon and very nice welcome from Carlo. Before even traveling, he sent us very useful information about public transport, nice restaurants, what to do etc. Once arrived at the appartment, Carlo was there again to explain everything and to help us find the nearest supermarket. The fridge was even filled with a nice welcome package for us! The communication with Carlo and Paolo (brother of Carlo with whom we had the first contact on mail) is SO quick ! You never have to wait even 5 minutes before you get an answer.
For sure, if you want a good place to visit Rome, don't hesitate to take this flat !
