For the moment, is the BEST apartment I have been via Airbnb. First of all, Rolando was very nice with us, waiting for us in the house, showing us all the things of the house, giving us advices about restaurants, etc. Even he gave us a bottle of wine as a gift!!
Otherwise, the apartment was perfect. The location is 1min to Ponte Vecchio, in a very living street, and you can go walking to every important points in Florence. The flat was clean, the wifi worked perfectly, the bed was big and comfortable, it has microwave, dryer, traditional Italian coffee maker, towels, blankets, etc...
Without a doubt, if I came back to Florence I will go to Rolando's flat!
