The location is perfect - quick walk to just about anywhere in Florence. The apartment is very nice, too. We found it clean, comfortable, and equipped with everything we needed and also thoughtful touches like umbrellas. Yes, there are stairs, but it's not much considering all the walking and stairs you do just from enjoying the city. We heard the carts, but they weren't bothersome and otherwise (and this may be why the carts are noticeable) the location is very quiet and off the main thoroughfares. We really enjoyed the place and would stay here again if we are lucky enough to return to Florence.
