We spent 3 nights at Giacomos place and really enjoyed our stay! The apartment is located in a lovely neighborhood, everything is in walking distance. The recommendations for restaurants and cafés were great! The accomodation was big and very clean. Especially the kitchen was well equipped so we could sometimes prepare food and have breakfast there. The hand-over of keys worked well, unfortunately we haven't met Giacomo. I can definetely recommend this place for a city trip to Florence. You should only avoid arriving by car, but this is due to general bad parking situation in Florence ;)
