This place is great! Where do I start? From the clear lines of communication from both Mauro and Chiara (Chiara, especially, was lovely, helpful and forthright via email before our arrival) to the hotel-level cleanliness and attention to detail of the apartment, to the fantastic location--off the beaten tourist path, but smack in the middle of the bustling local Florentine food/wine, literature, art, intellectual scene--Casa Lily is a gem. The air con in the bedroom was strong and cold (we were there during a heat-wave and needed it the entire time), the WiFi gave us no problems, and Mauro, the generous host he is, had left us a bottle of Proseco as well as fruit from the local market. Oh, and I should mention, it's easy to get to from the main SM train station, via a number of city buses that only take 10-15 mins. (Save your 12 euro cab fare and buy a bus ticket for 1,20 instead). My wife and I had an exceptional time at Casa Lily, and like another commenter already mentioned, we feel as though we have gained new friends in Mauro and Chiara. I hope, were they to come visit us in San Francisco, we could offer a fraction of the hospitality they provided us! As for us, we'd stay here again in a heartbeat. Gonzissimo!
