Our stay has been fantastic! Despite the heat wave, Mario installed a mini air con which proved to be useful. However, it was still a bit warm in the living room. The communication with Mario has been very friendly and fast! He even recommended a very nice place to have breakfast nearby the metro stop (which is 10min or so then to Duomo).
Also, Mario let us left our suitcases during the day so we could walked around without having to bring them.
The place is very cosy, charming and SUPER clean. We all had our own set of towels, hairdryier etc.
Overall I completely recommend! We had a lovely stay
