We loved the stay at Maria Cristina's! It was very spacious, well decorated and had great air-conditioning for the really hot weather in Rome! It's a very quiet apartment, and was a lovely place to unwind after site seeing every day. It's very close to public transport and all the major lines to take you to your destinations. It's also an easy walk to the city too!
There is a central square meters away form the apartment with groceries, gelato, restaurants and some bars!
We would recommend to anyone visiting Rome!
