Carsten's apartment was a great place to stay while in Berlin. There were some restaurants not too far of a walk away and in Berlin it seems you can get pretty much anywhere within 25 minutes on the train. The walk up the stairs is not for the unfit, but the view is very nice! Comfortable beds, hair dryer, all good.

Carsten even discounted the place when the terrace was under construction. I wish we could have used it, but it was very thoughtful to do so.
