We had a such a lovely stay at Sabrina's flat. She welcomed us herself and gave us a complimentary bottle of wine. The flat is very clean and comfortable and we struggled to get out of it everyday :) location is great, walking distance to main attractions and city centre. Also you can walk to Piazzale Michelangelo if you don't mind a bit of a climb. Plenty of good restaurants and bars around. Highly recommended and I'll come back again if I visit Florence in the future :)
