Valentina's apartment is in a typical neighborhood of Rome. It is very easy to get to from the airport (just get out at "Trastevere" station, change into the bus and go 10 minutes) and surrounded by all the local shops you could want: drug stores, restaurants, gelato bars etc. The apartment itself was immaculately clean with all the amenities one would expect plus then some! Towels, charging cables, even bottles of water and little snacks in the fridge. We came in a little late, but Valentina was very understanding, greeted us and made sure we were situated. We couldn't have asked for a better base for our stay in Rome.
Two restaurants in walking distance that are almost exclusively frequented by locals and that had wonderful food:
Trattoria Da Cesare al Casaletto (about 600 m from the apartment)
La Gatta Mangiona (about 300m from the apartment)
You can order food to take out - if you want to sit down you will need a reservation! We picked up pizzas at La Gatta Mangiona several times and sat down at Trattoria once and had a wonderful time.
