Cozy studio apartment centrally located within walking distance to the Colosseum, Trevi and most other main sites, as well as great restaurants and cafes. Checkin was smooth (just keep in mind there is a late fee for checking in after 8).
Well-equipped kitchen, the mattress was pretty comfortable but not very firm, especially in the middle with two people on it (fyi for those looking for firm mattresses), and as the other reviewers mentioned the shower stall might be a bit tight for some, but it wasn't really a problem for us.
I'd recommend Fabrizio's place to anyone that's looking for a place in a slightly quieter neighborhood but still walkable and close to all the main sites in Rome.
