I was a solo traveller on this occasion and can say the location is excellent. A walk from the train station with baggage is easily managed. You are then within a walk from all the major sites and lots of places to feed you body and soul.
It is on a side street so the noise from below was not an issue. There is however the noisy floor in the sleeping area which is the same in the apartment next door it seems. It was very noticeable, so maybe half a star lost for that at most. I didn't use the cooking facilities as, well this is Florence, why cook for yourself!? Roberto gave me some very good recommendations and also points to see and routes to take around the city. Check in was easy and accommodating.
