I was concerned that Oliver's place would be a little far out of town, but it is 5 minutes from the S-Bahn and 5 minutes from the U-Bahn. It's close to a great supermarket and lots of good coffee shops and bars. It was really easy to get to, and the self check-in was really easy. The flat is on the ground floor, but feels very secure with shutters and blinds. 5/5!
