This place is exactly as described. Neat and clean, highly accessible by easy public transit that takes you to the centre of Florence in a few minutes one way, and the airport in the other direction (Tram Line 2). Check in advance for how to purchase tickets and it's easy to get to the apartment from the airport and downtown.
Amenities close by, good restaurants, supermarkets, a park, and on the bicycle path to Florence. Most importantly, Nicco and Cecilia are excellent hosts. They promptly answer questions, are willing to help when you have issues dealing with a new city, and are honest and clear in communication and payments. Highly recommended.
