Maria's apartment was just what we wanted while in Rome. If you do not mind walking, which we found the best way to see Rome then I would highly recommend Maria's.
The apartment was very neat and tidy, had all that we needed in the way of amenities' and a great bed to go with it.
The longest walk we had was to the Colosseum about 20 minutes for us. You stay so close to Trastevere with its little markets and unending cafe's and restaurants it was a bonus, especially Mama Eats superb food and service.
Maria's apartment in Trastevere is a place to return to after a long day seeing Rome, quite and peaceful. I would recommend her apartment if this is what you are looking for in Rome then look no further.
