We didn't see much of Giovanni, but his welcome was fine and fuss-free. The flat is as described: colourful and central. (Two or three mins walk from the red line metro station). The neighbourhood is ordinary and safe-feeling; plenty of small bars and cafes, friendly with reasonable prices, not touristy, which was a relief after a day of sightseeing. We could have done with more than one airconditioner, but to be fair, it was a very hot week. The flat was well equipped for self catering, and it was a nice touch that basic supplies, presumably belonging to previous renters, had been left. We enjoyed our stay.
