My girlfriend and I stayed three nights at Carlo's place and enjoyed it very much.
The communication with Carlo was very good and he allways responded quickly. The appartement is clean, comfy and spacious. Very close to the city centre and the naviglio discrict. There is a tram and bus nearby and best of all a station of the "bikemi" bikesharing service. If the weather allows it, i really recommend to use the bike. Carlo was away, so Vittorio has welcomed us warmly and gave us some plans of the neighbourhood with recommendations where to eat or shop. If i am back in Milano, i'd definitely try to stay at Carlo's place again.
