we didnt have the opportunity to meet lorenzo, but his father was there the time we need to check in. the appartment its close to the heart of the city, about 10-15 min. i recommend to rent a bike at san zanobi, 500m from appartment. appartment was fully equiped,very clean. bit small for 4 people, but i highly recommend it if you intend to explore that beautiful city. very quiet and safe neighbour. you can park your car at the road for free.
hope i get back one day
