Alan was on vacation, and his colleagues checked me in - it went smoothly. The flat is very clean (shower is amazing for Berlin!) and is in a really good location. Transport, food, convenience stores, bike rental, park - everything that you might need is very close by.

I also liked that the flat was on the ground floor with a very easy access. It can be noisy, though (can hear people talking outside & cars passing) - so would recommend to take earplugs.
