My wife and I stayed in this apartment for a few days during our trip to Berlin. Check in was fast and easy, and the apartment was lovely, with everything we needed for our stay. Special mention for the bed (really comfy)!
The location is what really did it for us - right by a U-station and a stone-throws away from a really nice coffee shop, which we started off the day with every morning.
Highly recommended for a city break - thanks again Trudy!
