We were only here for 2 nights but it fit all our needs. It's very close to the train station as well as the Colloseum and Palentine Hill. The beds and rooms were comfortable and there is a large dining table where we could gather and plan our day. Our contact for the apartment was very helpful and gave us lots of recommendations in the area as well as a recommended itinerary from the apartment. Another notable plus was that the apartment was very quiet for it being right off a very busy road.
The only issue we had were the showers. If you are a larger person you'll probably have a hard time using the showers here. Otherwise we had a very pleasant stay.
