If you are only visiting the Vatican, then this a great location - within a 10 minute walk. It is close to the metro but many of the major sites were not that close to the metro so we did a lot more walking than we thought we would.
The wifi was not working very good. We always had to keep logging into the network once we came back to the apartment and there were times when the wifi was very slow and/or did not work at all. We also had to pay 3.50 euro/person per night so we had to pay an extra 10.50 euro for each night which I did not expect.
Overall, the experience was average. We expected more for the amount of money we paid.
