Me and my friend had an amazing time in Florence thanks to Breditz and Nadja. They were very nice, helpful and gave us great advice on places to go to. The location of the flat is probably the best you can have in Florence, since it is directly at the Mercato and cathedral. All other things, also parks and piazzas outside of the touristic area are easy to reach by foot. The room was very comfortable and nicely furnished. The whole appartment was decorated in a Tuscan style, which was very beautiful. To our surprise they also offered us a breakfast.
We will definately come back to Florence and stay with Breditz and Nadia :-)
