Luca showed up quite quickly despite that I arrived earlier than expected. He seemed nice and helpful. After he left, I was completely on my own, which gave me a lot of privacy. It was really like I was in my own place. That was the best thing about my stay.
The place itself was clean and nice, and the location was reasonable both for walking around and using the public transport. You should expect some street noise early in the morning (perhaps like everywhere else in Rome) due to the hyperactive public transport system.
