I spend two months at Franziska's place and have nothing but good thing to say about it. First of all, she is friendly, nice, tries to help you to best of her abilities. The place itself is also super nice, clean, beautifully furnished and I think the location is perfect.
Honestly, I couldn't have asked for a better host and place. If you have the opportunity I definitely recommend staying with her. I'm sure you won't regret it.
