I had the pleasure of staying at Federico's B&B for 9 nights at the start of June. I can't say enough great things about this place! I loved the location - it's central enough to walk almost everywhere within 10-20 minutes, it's just outside the bustling tourist area so very quiet and not at all crowded, and the neighbourhood has a great vibe - very casual, bohemian and artsy. I would sum it up as eclectic. Monti boasts some great restaurants, most of which can be reached on foot in less than 10 minutes. The B&B is super close to the Colosseo, Foro Romano and Piazza Venezia as well. The B&B is between two metro stops - Repubblica (red) and Cavour (blue) as well.
Federico was super responsive pre-booking, in the days that led up to my arrival, and during my stay. He always responded quickly. He will take the time to show you the B&B, explain how everything works, show you the layout of Rome and give you a few maps along with restaurant suggestions and directions. I also took advantage of his car service, as I flew overnight. I highly recommend Domus and hope to stay here again!
Breakfast was fine and each room had a daily selection of salumi along with cornetto etc.
