Short version: if you have a party of 2-4 people and Matteo's place is available for your dates, book it now! I can't imagine a better riverfront home base from which to explore this fascinating city.
Long version: Staying in Matteo's apartment--directly on the north edge of the Arno river--gives one the feeling of an artist friend having given you the keys to his bohemian pad in the beautiful center of Florence for a few days. This "friend" also happens to be immaculately tidy with a keen eye for design: the books, art and decorative objects make the apartment feel like a home but without any hint of clutter. The space is well designed, with 1.5 bathrooms and the ability to make the two sleeping areas completely private or to open up the full floorplan as needed. Matteo has thought of virtually everything, from dining recommendations to clear instructions on operating the washing machine. Everything you need is provided (laundry soap, shampoo, bathroom essentials, bottled water etc.) and the amazing windows provide spectacular views of the Arno and the city to the south. You won't regret a thing about staying in this wonderful home where you will indeed feel like you could reach out and touch the Ponte Vecchio! For our family of three it was the best lodging experience throughout our Italy travels, and Matteo is by far the best AirBnB host we've ever encountered.
