This apartment is truly phenomenal. It's like staying in the grand suite of a 5 star hotel! Everything is beautifully and tastefully done, it's very quiet, and having the little terrace is lovely. The location is exceptional -- just a few meters from the Piazza Duomo. Brittany was not in town and we were taken care of by her very gracious and helpful colleague, Jeffry. He met us at the apartment, shown us how everything worked, and gave us wonderful suggestions for eating, drinking, and visiting some sights that are not featured in some of the guides to Florence. We will most definitely stay here again.
PS: I recall in one or two of the reviews that I read before booking say that there was construction noise. We heard a little bit of noise (about one hour tops) on the first day there but did not hear any other noise during our 4 day stay.
