Massimo was really responsive, and approved of our stay quickly. He is a very laid back guy, didn't seem to worry too much about any problems, and responded quickly to my questions.

My coworker and I were staying there for a weeklong conference at Consiglio Nazionale delle Ricerche (CNR), which was only a 5 or 6 minute walk. A couple of great restaurants in the area, but to get to the real "touristy" areas, the walk was close to an hour. Very close to termini. However, given that we were there for a professional conference, it was a bit awkward to show up and find only one bedroom, despite the listing stating that it's two bedrooms. There is a pullout couch that is very comfortable, but the bedroom is more isolated from the noise of the bar downstairs.

Overall, Massimo is a great host, and other than the bedroom issue, the place is exactly as described.
