What a great place - we loved both the flat and lcocation! Tom & Arzu were really helpful. We'd definitely recommend it and stay here again next time.
We enjoyed meals at Lindengarten so I'd recommend there. The brewery Eschenbrau looked great but we ran out of time (they don't serve food but let you take kebabs in from Luxemburger strasse apparently).
If you enjoy the natural world, especially birds, then I highly recommend a day out with Rolf: http://www.birdingberlin.com/
Marvellous day - great to see the countryside outside Berlin and we learnt lots from him.
