The apartment was perfect! Wonderful central location with a short walk to the main area of Florence. The kitchen was good for the option of self catering but there was also a lot of good restaurants close by. It gets a little hot but this is expected, and the air conditioning solves this. Great bathroom, and towels included. Elena and her husband are very accommodating and friendly, and gave us good information about the area.
It's also super easy to find, being around the corner from the train station which is very accessible from Pisa Airport.
Also we would recommend La Boite, a small local bar just down the road!
