We had a pleasant stay in Giorgio's apartment and he was flexible with checking in and out.
We were a bit surprised with the fact that all radiators were on full heat when it was 20+ degrees outside. It made the apartment uncomfortably hot when we returned at night, so keep an eye out for this as you can adjust them yourselves.
Giorgio responded well through the Airbnb site, but I did not receive answers to my WhatsApp messages to him. This was however not anything we had agreed upon either, except from me calling him when I arrived so that he could let me in.
The location is excellent and the stay was great so we would be happy to stay again :)
