Great place and an outstanding host.
Giovanni's place is located very close to San Giovanni metro and has some great places to shop right near the house. Lots of places to eat, including the trattoria in the adjoining lane (can see this from the terrace).
Giovanni helped sort out the issue we had with the toilet and was a great host. Quick responses and a warm personality.
A couple of points to note - the apartment has centralized AC and heating so it doesn't work till the entire apartment complex determines it fit to work. And there are about 15 odd winding stairs since this is located between floors. Elevator takes you to the floor and then you need to take the stairs.
All in all, a great stay.
