Su is incredibly nice and attentive host. We arrived very late and she was waiting for us, let us in, told where we can eat after midnight and did everything to make our stay as comfortable as possible.
The apartment is really cozy and has everything you might need (fridge, microwave, high-speed wifi), the bed is very comfortable. There are a few supermarkets and restaurants with low prices around. It takes 10-15 minutes to get to the centre of Florence by train.
Su, thank you very much for your hospitality! If we come to Florence, will definitely stay at your great apartment again! :)
