Location is good, nearly 15 minute walk from Termini train station. The metro station is also close. The place itself is nice, not as new as it looks in the photos, but overall it's ok... there is no common area except the small kitchen, where it is possible to prepare some light meals, however, no one comes to Rome to stay at home...))) so we were out most of the day and it didn't really matter for us...
Communication with Riccardo was very very easy. Check-in was quick and informative with the tourist areas as well as recommendations on places to eat.
We recommend this apartment.
