Perfect location! I loved my stay at Ranieri's house, extremely central and very easy to reach (just off the Dante metro station).
Ranieri was a very helpful guest giving good indications to visit the city and its best restaurants, responsive to all my requests. The room is exactly like in the picture, very nice and stylish. It has no window, but the living room - very large and nicely furnished - has two big windows/doors.
Wifi in the room didn't work all the time but it worked well in the living room, separate from the rest of Ranieri's house and shared only with airbnb guests or another room.
