We arrived quite late at night so we never got to met Andrea. We found the location really handy. It was on the same block as a small supermarket, a laundromat within a 10 minute walk, and some very good restaurants a stones throw away.
It is very close to a metro which easily connects you to the Vatican City. All other attractions are a easy walk away.
The apartment was lovely. If you put your head out the window you can see a sneak peak of the colosseum. It also looks out on some old ruins which was fantastic.
We were in Rome at a very busy time, everyone was out celebrating the FIFA World Cup or on summer holiday. As there are a few pubs close by (one three floors down) it can get a bit noisy. We didn't mind this so much as we were in and out a lot. The bed was a bit firm however, in my experience this is how the majority of beds are in Italy. The only thing missing from the apartment was a washing machine, for long stays this would be handy however as I said above, there is a self service laundromat within a 10 minute walk.
