Duccio's apartment is very nice, and above all situated in the very heart of the historic city, so useful to visit Florence by feet ! The apartment is spacious and clean, we were only very hot even with the air conditioning, but that was mainly due to the summer weather. We didn't get the pleasure to meet Duccio, but everything was well organized so that we could get the keys without difficulty, and Duccio was very reactive to answer us when we couldn't find the wifi's password. On the overall, I highly recommend this place ! Be only aware that there is no elevator, it's only on the second floor but could be complicated for someone with walking difficulties ;-)
