Daniela contatec me several days before I arrived and sent me message quit clear for reaching her apartment .The flat is quit nice ,clean and safe. It is around 10-15 minutes by walking from train station, if you carry your luggage. Beside the apartment, it is the centre market, you can buy lots of food there , and around 10-15 minutes walking , you will find most of the important points of Florence. Anyway, it is really easy to reach everything.
