The apartment made a good crash pad from which to explore Berlin. There's very little common space, so don't plan to spend much time in the apartment itself. The beds are comfortable and the kitchen comes equipped with anything you might need, but the hot water tank is fairly small, so make sure to take a quicker shower if you want hot water! Also set a precise time for check-in, as the key is delivered by a porter whose time is inflexible. Heads up that you'll have to sign an inventory sheet as well as an additional agreement regarding the state of the apartment.
