This place is all about LOCATION. If you want to visit Rome and see all of the sites this is the place you need to be. The value is unreal, the location is perfect, and the communication with the host is exceptional. We spent three days here and it was perfect. We were able to easily get everywhere on foot (including the Termini train station) and when we wanted to visit the Vatican or catch a bus a little further both the metro stop and bus stop were very close. There are awesome restaurants right down the street and I highly suggest making a stop at them at least once while visiting. The ideal location allowed us to explore in the morning, swing by the apartment mid afternoon to relax and refill water bottles, and head back out for a second round of site seeing.
The apartment is older but it has everything you need to be comfortable for your stay.
