I had a great two bedroom AirBnb in Florence when I went summer of 2016. Unfortunately, the owners no longer rent it through the site or else I would link it here! I shared it with another TDH and fellow NYU classmate. It was perfect for us-- a quick 5-10 minute walk to the dance studio, had a washing machine right in the apartment for all our sweaty dance clothes, and had air-conditioning! Giada always recommends that we find a place to stay with air-conditioning and I cannot stress enough how much of a life saver it was! July in Italy is HOT and the dance studios do not have AC so to come home to a cool apartment was necessary.
