My friends and I had a lovely stay at this Vatican apartment. We had plenty of room for the 5 of us to spread out and it was nice to be in a first floor unit.
The location was good, with a bus stop right outside the door and about a 10 minute walk to the nearest Metro station. We did take a lot of taxis but the rides were fairly inexpensive to our location from wherever we were in Rome.
It was nice to have a kitchen as we made coffee and ate dinner in a couple of nights. There's a grocery store a few minutes away that provided us with all the bread, cheese and wine we could want! There's also a great restaurant /bar nearby called Il Pappagallo with wonderful drinks and gelato.
I did not personally meet Guiseppe as another member of our group arrived first and got the keys, but he was always very responsive to any questions or comments and we would stay there again!
