We had a wonderful time staying with Bred and Nadja! The apartment is gorgeous and so close to the centre; you can walk to the Duomo in about 3 mins, and you're a street away from the amazing market, where we had several lovely meals! Bred met us personally and made us feel very welcome- he told us about the best places to visit, eat and drink, and his recommendations were all spot on. We'd definitely stay here on our next trip to Florence!
