Giovannis apartment is the perfect place for your Roman holiday. Everything as advertised, clean, spacious. The street is extremely busy with tourists (and tourist shops and mainly touristy restaurants), so be prepared for all the bustling, but the beautiful courtyard of the building and the apartment itself are quiet. The light in the open sitting/dining room and kitchen is a bit somber as windows are low, but that's actually an advantage during hot days. Communication was easy; a late check-out was possible for a small fee.
I recommend Giovanni's place and would happily return there myself.
