We had a wonderful stay at Next Stop Colosseum B&B! It is a great location as it is very very near a metro stop, which can get you to most of the sites and to the main train station (Termini). You are also a short walk from the colosseum and Roman Forum if you choose to walk, and it is a relatively direct route which is hard to come by in Rome :) Breakfast was just a little heavier than the 'typical' Italian breakfast, so that was nice for us Americans. I speak Italian so I cannot speak to how our experience would have been if we were relying on English with our hosts, but they were very welcoming and easy to work with. Overall this is a great price for what you are getting, the room is big and everything is very clean!
