Enrico's place is located in a perfect area in Florence: walking distance to train station and Duomo as well. There are also many good restaurants near the appartment.
But you have to be aware that it is situated on last floor of the building so you will have to climb a lot to reach it. It is a very old flat so the standard is low (but the price is low too so we were not suprised). The thing I didn't like (and I think it is unacceptable) was dirt. Room downstairs was full of dust, bathroom (especially the bath) was dirty. I had to clean it before we could use it.
