Great flat. Really close to Oostkruez Station, which made getting to the Brandenburg airport really easy in the morning.
Nice to have a little outside terrace too.
We went in winter and the flat was warm and cosy. Easy check-in and checkout. Good facilities. Really nice large bedrooms with comfy beds. The two main bedrooms (both large) do lead into each other though. It wasn't a problem for us, as we were a group of good friends together.
