Paolo's place is not exactly centre of Rome, but it is much closer to the Vatican and there is metro station about 10-15 minutes walking.
He's a fantastic host, even with our delayed flight and late arrival he managed to greet us and give us a tour of the building and apartment.
The place itself is quite alright, 1 bedroom apartment with everything you would require (amenities, snacks, kitchen stuffs etc.)
One tiny issue was that the heating itself was not working properly and most of the time the apartment would get really cold as a result.
But all in all, a good stay and would recommend this host!
