The apartment is fabulous - it's exactly like the photos except better :). The whole apartment is really spacious and very comfortable - it has everything you would need for a short or longer stay.
The location is wonderful - close to all of the major historical sites as well as lots of different restaurants and bars.
Natali was terrific - very helpful with lots of information about what to see and do in Florence. If (when!) I come back to Florence I would definitely stay here again (assuming it's available of course!)
