We had a great time at Kerstin's coach house. Her place is smack in the middle of hip Prenzlauer Berg. The Kulturbrauerei and Mauerpark are close by, as our countless of superb bars and restaurants. The apartment is super easy to get to, very close to the U2 and M10 lines that will get you to Mitte in no time. We had a two-hour delay because of our flight, but the cheerful reception we got from Kerstin made us forget all about it. Couldn't recommend more!
