Great little apartment, perfect for a couple, shower was great and the only downside was the tv being tiny, but who needs a tv when you've got the whole of Berlin to explore!
Josef had to let us in at about 11:15pm after our flight was delayed, but he was a total gent about it and there was a bottle of red wine waiting on the table for us when we arrived. It's only a ten minute walk to the station and once you get the hang of the trains you're sorted.
