We stayed in Maria's place in July, one of the hottest months in Rome. The air-conditioning was a god send. The apartment was perfectly located, walking distance from most of the major sites, including the Colosseum and the Spanish Steps.
The apartment will also comfortably accommodate 2 couples with one double bed in a bed room and a surprisingly comfortable foldout bed in the living room, both of which have their own doors for added privacy.
The bathroom is separately accessible and has a shower and the usual amenities. There is also a washing machine we made use of as our clothes needed some refreshing after several hot days of site seeing.
All and all a great little place to stay in Rome if you want to see the sites of the city and get a feel for Roman city living.
