We very much enjoyed our stay in the Old Town flat. The area is lively and there is no reason to venture far from the flat to get a great meal (gelato is steps away from the front door) and enjoy an evening of people watching as you sit on the fountain steps in the plaza outside of Santa Maria. However, when you decide you want to visit the classic sites of Rome they are all (from the Vatican to the Colosseum) within a short walk from the flat.
The room is small and simple (the shower was not built for a 190 pound American) but accommodated our needs. Federico went out of his way to make sure that were well taken care of. When the air conditioning struggled with the 98 degree days of late July, Federico addressed our concern quickly and brought us a fan that cooled the room nicely.
If we are to be so blessed as to return to Rome and the Old Town flat is available we would book it again.
