I spent 3 weeks in Hedda-Maria house and highly recommend staying in the room she offers. Everything was as described: the neighboorhood is really quiet, but still with a good access to public transportation at any time. The space (room and private bathroom) has a separate entrance and the only space you share with the host is the kitchen. If you're stick to the house rules (especially regarding using the shared space), you can have pleasant and carefree stay. The host is really nice and warm person. During my stay I've never felt unwelcomed, and the communication was also very good.
