We enjoyed the central location, the cleanliness and the fact that we were able to check-in early! As an approvement we would suggest a new mattress because it's very thin and we could feel the slatted base underneath. Also a new shower curtain or a shower door that properly closes.
Another detail is that it's located above a tiny supermarket, which is convenient on the one hand but on the other the owner of the shop was chatting loudly under our window with friends 'till late in the evenings. No midnight business though, so in the end we did get our sleep :) around the corner is a nice coffee place to have breakfast we very much enjoyed.
All in all we were happy to stay at this place and explore Rome from there.
