Our experience at Nadja's and Breditz's was short but very nice. We had very little time in Florence, so the great location was very important to us. It can be a bit noisy at night for light sleepers, but it was fine for me. As with many old buildings, there was no elevator, but the stairs were wide and not too many. The hosts were there to greet us and gave us great tips. Would definitely stay there again if going back to Florence.
