The apartment was as described and easy to find. It is not really center but 15 minutes walking on the Arno river sight you will arrive at Ponte Vecchio and from there you are near everything. I guess if you arrive from Santa Maria Novella train station (make sure that coincidence with their check in time) it is 10 minutes walking distance. A wifi connection will be nice but I guess being in Florence you are most of the time out and you can find lots of places where they have Internet access. Mr Carlo was very helpful and we did not have to wait for check in, he was there in 2 minutes with the keys.
