Great option for staying in Berlin. Jurgen is very punctual and well organized host. Both check-in and check-out were very smooth, we were even allowed to check-in couple of hours earlier. It is easy access from the Hbf and a U-Bahn station. The apartment is on the 2nd floor with an elevator. You'll have a comfy bed, a washing machine, a dishwasher, a coffee machine, cable TV, Neflix, a ceiling ventilator (no AC, but that was ok in June). Definitely recommend this option.
