Marco is a wonderful host, he's across the hall and attentive and responsive but not intrusive. The apartment was perfect for me. Loads of space, perfectly clean with everything you need. The location is amazing, surrounded by great restaurants and bars, close to the river and walking distance to all the sights. In Oltrarno it's in an up and coming neighbourhood and away from the tourist madness (still close enough to easily get everywhere on foot!). I loved it and extended my stay.
