Had a wonderful stay in the apartment! Lots of natural light, loads of history in the building (even with a few pieces of the Berlin wall set in the courtyard behind it), and overall lovely stay! The door lock is a bit confusing (turn the lock RIGHT not left) and the mezzanine bedroom was a bit tight going up and down the stairs. Also the stairs going up to the apartment are quite a lot with big suitcases. But all in all though it was quiet, comfortable, and delightful experience! Also in a fantastic location right near lovely cafes and the train. Would recommend to anyone!
