By Modi is 100% recommended! He is really kind and nice person, he is so flexible and relaxed. So comfortable with him. In the kitchen he has full of italian good foodstuffs, and you can use them. His advice for the town and sightseeing was really helpful.
His apartment is simple and very clean, you have own bedroom (big double bed) with big window, the Bathroom is big and clean. The apartment is near from Ponte Vecchio and Palazzo Pitti, very nice quarter. To center of Firenze, you can go by foot very easy.
When you wish free-style travel and to feel real italian life, by Modi is perfect!
