As others have said Monica's apartment is very spacious - bigger than the impression given by the photos.
Monica was a lovely host. Communication before, during and after our stay was easy and fast. We were struggling to find information on an event in Rome and Monica very kindly made enquires for us before we arrived. Monica met us at the apartment and explained everything to us.
The apartment is on a road with trams but the bedrooms at the back of the apartment are quiet and we were never disturbed by road noise. Some of the bedrooms do not have air con and may be uncomfortable in height of summer. Internet was fast and reliable - I brought my firestick so I could watch my football team on the large screen TV. The kitchen is fully equipped with everything you might need.
Location is great - less than 10 mins walk to two metro stations, 2 mins to a supermarket and 20 mins to the Colosseum. Piazza Vittorio just 2 mins away is a lovely green space we enjoyed in the evening. Gelateria Fassi opposite the apartment is a must.
We would recommend Monica's apartment and would happily stay again
