We spent four days at Sonnenhaus and really enjoyed the food (didn't miss anything despite it being all raw and rather simple dishes - super tasty and filling nonetheless!) and the atmosphere. We had a super cosy and clean room, there were lots of toys for our daughter in the common area to play with and we had very good chats with the owner Elke who has been raw since before I was born.
Sonnenhaus is also conveniently located for visits to hanse town Lübeck - there is a bus to the main station which takes about half an hour. I would recommend this place to anyone seeking for raw food and relaxation in the north of Germany.
