We had a very good time staying at Enrico's. He was a very good host - communication and check in were very easy and he even helped us with quite a few recommendations. Subway is 2 minutes away and the Vatican is at a walking distance from the apartment. The neighborhood is relatively quiet, but with lots of good restaurants. Supermarkets and pharmacies are literally a few steps away. The place is perfectly sized for a family of three and has most of the things one would need in order to feel right at home. One of the few small issues would be the water pressure in the kitchen which made it hard to wash the dishes after eating, but all in all I would definitely recommend staying at Enrico's place :)
