Unfortunately we didn't have the pleasure of meeting Claus but we were greeted by a lovely lady. We had slight trouble with communication but with a few hand gestures we understood one another. All was pretty self explanatory anyway.
The flat had a lovely view, of course, and all amenities were present.
It's a luxurious place. There are no curtains which bothered me slightly but not my husband. The light does get you out of bed sufficiently early for a Berlin day. Claus provides eye masks at any rate.
There's a tabac close by and 3 stations dotted around you. All within about 10mins walk.
Paul-Lincke-Ufer has a great Turkish market on twice a week and on the other side of the canal are some nice restaurants. Spindler for brekkie, hardwax for music, Cocoloco for good hip Ramen. Again about 10 mins walk from the flat. Another great place was the street food market at Markthalle Neun on a Thursday night. About 20mins walk, but a nice walk.
These are all things we discovered in the area, which is to say there's a lot around you. And when you're done with that you can head back to a pretty cool flat.
Great 5 days I must say.
