A perfect stay! The apartment is exactly as described, except even closer to the duomo than it seems in the pictures. Ciro graciously forgave us for being late (we couldn't get a taxi from the parking lot where we left our car) and gave us a very thorough tour of the apartment. He is a lovely host.
It is a very lively location, so be forewarned: if you are looking for a quiet retreat, look elsewhere! This is in the very heart of Florence, and is just as exciting and noisy as that sounds. We loved it.
