Luca was a great host and helped us resolve a couple of minor issues with the heat. Kitchen is very functional and laundry machine extremely useful. Supermarket is on the same block. The duplex spiral staircase can be a bit challenging as it is narrow and hot water is enough for one longish shower until it needs to reheat. Location is amazing. Suggest you seek out Galileo Museum, Bardini Gardens, and Alessandro Dari Gioielli Jewelry Museum in addition to the major sights. Paying for a guided tour of the Duomo dome is worth it. Side trips to Lucca and Sienna by train are great too.
