Very clean and well-located residence, and a flexible host! I was able to check in a bit earlier after discussing all the options with Helga. I was given very detailed check-in instructions including pictures and possible difficulties to expect using keys etc., but I had none and found the keys and the flat with no problems at all. I didn't expect to need the clothes washer, but it was a welcome addition to the amenities after a long holiday in Berlin! Thankful for the elevator as well after a long day or walking about town, although I made myself take a stairs a few times haha.
