We didn't get to meet Stefano as he was sick at the time. Maria met us, gave us keys. We were running late for our schedule and Maria kindly drove us to the Vatican. On the day we left she also drove us to the airport for 30 euros which is a very good price.
The place is clean and well furnished. However the location is a bit far from downtown. There's a bus stop close by but buses in Rome don't always run on time.
In my opinion it's better to take the Metro.
There is a 24 hour grocery close by which is good.
Finally there was no WiFi which nowadays is very important when you're traveling. You need it to plan your trips, check in to flight etc. I hope they fix that soon.
