We really enjoyed this place. It was clean and spacious and in a really great location if you don't wish to be in the very centre of the tourist areas. Very easy to walk to the tourist areas like the colloseum, trevi fountain, Vatican etc in 10-30 minutes.
The only point to note is that on weekdays there is a glass rubbish pick up truck that makes a lot of noise around 7/8am. If you are awake by then it won't be a problem but it does wake you up otherwise. Also if you are a light sleeper note that it is street level so will be a bit noisier. These weren't massive issues for us but it is something to be aware of.
