We stayed in Axel and Anne's flat on our first visit to Berlin and weren't disappointed! The flat is quite central but you need to take the s-bahn to get to see the sites. This is only 5 mins walk away and very easy to use, even for novices like us. The flat was clean, tidy, warm and in an enclosed court area so very quiet. There are lots of restaurants and bars nearby so no need to go into the centre of Berlin for dinner - the suggestions Axel gave were amazing ("the bird" for burgers amongst others). We also went to an awesome Indian called chutnify which was probably the best I've ever had.
We had the check in late and axel was very accommodating and sorted out a place for us to pick the key up which took a lot of stress out of the whole trip - very grateful.
Overall, a great stay in lovely accommodation. Will definitely return!
