Our stay at Maison Imperiale was very pleasant. We stayed in the large suite. If you open the window and lean out, you can see the Colliseum just down the street. An excellent location! The room was spacious and comfortable. We were pleased with our stay. Breakfast was somewhat minimal with toast and jam and store bought sweet things in wrappers, but that was OK. If you want a better breakfast, visit the cafes on the same block. Let me mention a few problems not because they were serious, but because they were minor and easy to fix.
This is not a hotel, it's a bed and breakfast. It is located in a building on the second floor (1st in Europe) in a suite of rooms. This should be made explicit in the listing. Our cab from Roma Termini got us there very quickly, but we were looking for a sign, something to let us know we were in the right place. It took a long time to discover the name on one of a dozen doorbell ID signs at the front door. Customers should be explicitly told how to get here and how to get in when you do. Another issue, common in rented rooms, is the absence of a place to put your soap in the shower stall. The shower arm was loose and had to be tied to the rod to stay up and the beautiful new tiles were, I guess, too pretty to drill a hole for a soap dish. Finally, even on a hot summer night, with AC running, it's nice to have a blanket in addition to the sheet. There was none in the room.
