I stayed at Gertrud's lovely apartment for 4 days with a friend and we felt right at home straight away. The room is small, but definitely sufficient and we took full advantage of the kitchen and spacious dining room. The apartment is well located, with a market on the corner and bus stops and train station nearby. It is an easy bike ride away from the city centre. We hired bikes for the majority of our stay and there's a basement where you can keep them overnight. Gertrud was very friendly and we would highly recommend staying with her.
