The place is situated in a very central location of Florence.
From her place you can walk to all sightseeing within 20 min (To Doumo is about 15 min)
The host also stays in the same apartment and my room was next to her.
The room was pretty big and could fit 3 persons (I was there alone and I thought it was already a reasonable price for 1). If you split the cost my 2or even 3, this will be very cheap.
