Mirko was our host and he was wonderful! His English was great and he was very helpful. On our second day, we could not get the lock open on the door (tip: only turn the key to the left and pull on the doorknob and it will open very easily!). He made the 15 minute trip right over to us to help us. Magnifico! Couldn't ask for a better flat. Great location, simply lovely, Duomo views are spectacular, towels were the best of any Air B&B we've stayed in and most importantly for a summer in Firenze: the A/C works GREAT! Lack of toilet paper was a problem but we bought TP and paper towels for the unit. Will definitely be coming back. Grazie mille to Riccardo and Mirko for having us!
