Alessandro was very easy and straightforwardly.
Sadly the WiFi didn't work, but it wasn't his fault.
You can reach the vatican in 20 minutes with the metro. (10 minutes from the apt. to the station, 5 minutes in the metro, 5 minutes from the station ottaviano to saint peter)
It's really low cost for Rome, but u can't expect that all will work. (For example the shower doesn't work really good)
