We could not ask for a place that was better located. Right across from the Medici chapels, surrounded by restaurants and minutes away from the open markets and the food market, Cosimo's place is perfectly located. It's a very nice quaint place with large windows and a small living room with a view of the chapel and the cobbled streets of Florence.
They were a little strict about the 10a.m. check out policy, but were nice enough to store our luggage till the evening. Overall our stay was very good and I would come back to this AirB&B if I were to return to Florence.
