Although I never met Manfred he was very easy to get hold of and replied very quickly to messages. The flat looks exactly like the photos and was immaculately clean! Had helpful tips about coming from and going to the airport regarding tickets. Had an iron available too which I needed as I was attending a conference. Less than 5 mins walk to the U-Bahn and within the city centre in no time. Lots of supermarkets nearby too for self-catering purposes.
Thanks for a lovely stay!
