We've had a really wonderful time in this lovingly refurbished garden house. The location is really charming - the woods start right behind the house.
Our children really enjoyed the garden and the huge trampoline. Having a bike was great for access to local shops and the bakery, and the transport connection via S-Bahn into Berlin is in easy walking distance.
Sven and Sandra were lovely hosts and always there to answer questions.
The only thing to look out for is that the ceilings in the upper level (where the two bedrooms are) are rather low, so you can't really stand upright. It wasn't a big issue for us (the children in fact loved their sleeping 'den') but it's worth knowing.
