Isabella's place was wonderful. Recently remodeled and very light and airy. Great views from the terrace and the kitchen window.
Easy walking distance to the Duomo and the Accademia if you are used to walking (about 20 min. by foot to the 'downtown' retail district). The city buses are available s a block away if walking is not your thing. Good restaurants and pastry shops within 10 minutes walking distance, across the Lungarno Benvenuto Cellini, in a neighborhood south of the Ponte San Niccolo. Or about the same distance north on Via di San Niccolo there are many nice osterias. Michelangelo Plaza is just up the hill behind the apartment.
Florence was a beautiful and majestic city to walk around and Isabellas apartment was a fine place to see it from.
