Perfect stay, perfect hosts, perfect location.
We are a family of 2 adults & 2 children, the apartment was perfect for us in many ways. It is located on the 2nd floor but has a lift if you are feeling tired. The apartment is located a 2-minute walk from Trevi, again, perfect location. The main bedroom is very quiet as it faces the internal gardens/courtyard, the other bedroom gets a little more noise as it's on the main street - if you are a light sleeper you may want some earplugs but it's not too bad considering.
The apartment is well equipped and hosts made us very welcome. Would highly recommend.
