The apartment was great. It is exactly as pictured. There is some graffiti on the building but it seems like every building in Rome is tagged so that didnt bother me and that is outside of the host's control. It seems to be a decent area and we never felt unsafe.
Very close to the train station and #64 bus stop which makes it convenient to get to some of the more distant attractions and termini station. We we able to walk to St Peter's basilica in about 15-20 minutes though it's a bit of a walk to the other attractions so you may want to take the bus or uber.
The host was very responsive when we needed him and I have no reservations in recommending this property
