We had a very nice time at Graziano’s place. The appartment is well equipped, full of light and clean. If you don’t mind walking, it is about 15-minute walk from Porta Romana. Or you can catch a bus at a bus stop which is max. 5-minute walk. Graziano is a great host, replies very quickly and is always helpful. I can only recommend staying at his appartment. Enjoy Firenze!
