My wife and I enjoyed our stay at Federico’s place. The location is absolutely perfect, right off of campo de Fiori and easily walkable to all the historical sites in Rome and a little further but manageable walk to Vatican City. Our incoming train was delayed and the host even waited for us an hour to facilitate the check-in process. There were a list of restaurants in the house that we took advantage of. As others have mentioned, there are a lot of steep stairs, so probably not the best option if that’s a problem for you. The only area we think could use some attention is the bathroom. The toilet would run unless you tapped the button again and there appears to be some mildew in the bathroom shower and ceiling.
