The room has plenty of space as well as charm. It is located rather perfectly. Many sights are within reasonable walking distance (max 30 minutes), and a metro station is very close by for all the others. The immediate neighborhood offers a wide variety of nice spots and culinary options.
Sabine and her husband were very welcoming hosts. I always felt like I could approach them with any questions or problems I might have.
All in all, I can definitely recommend them :)
