Modestino is the perfect Air BnB host. Welcoming, friendly and with a good tip or three of where the good wine and food is around the neighbourhood. Any history nerd will get a kick out of the fact the house was once owned by GG himself, but it does have its drawbacks - namely insulation, or lackthereof - we were there in Winter and we were FREEZING every night, even after running the heater for 8 hours during the day. Other than that it is quite pleasant, in the non-tourist part of town, near San Spirito piazza so there's many bars, cafes, restaurants to busy oneself with. The bed and shower were okay - a bit of a mould smell in the bathroom but that's to be expected in a 1000 year old house and as long as the fan was kept on, it really wasn't too bad. The 20 euro cleaning fee for what is no more than 25 sqm of space however, is a bit steep.
