We couldn't meet Giulio unfortunately but he has been very professionnal and attentive while we were there, reacting almost in the minute to every message we sent and providing all the necessary information on demand.
Location is really great: quiet flat, 5 min walk from very lively places to have dinner and go out in bars. Very central to visit Roma.
NIce flat, with all the required amenities. It's good to feel whatever you need is in the flat. Yet bathroom and mezzanine have a low ceiling... not for over 1,80m people.
Special plus for the very comfortable bed !
I would very probably try and come back to GIulio's flat if I went back to Roma !
