I had a short 4 day stay at Nicola's place and it was great. He has great instructions for check in and is extremely responsive and communicative. It's super clean, very comfortable and has everything you need. Someone on here said there was a great hair dryer and she was right! LOL! It does make a difference! I had been staying in Trastevere (with a really crappy hairdryer) and saved the Vatican and other places near by until I was staying here. As you can see, it's SO close!! Made it very convenient for an early morning tour of the Vatican. But still, if you are walker you can get to everything in city central easily!
The only thing that was a problem were very loud travelers staying next door. The walls are thin and I could hear ...uh... EVERYthing. if you know what I mean. But i think with most folks it shouldn't be too bad. Wouldn't be a deal breaker. Oh and the washer and dryer are in the corridor and shared with the other units. Not a problem, just wasn't aware so sharing.
