My girlfriend and I were a Birgit's place for two nights and had a lovely time there. For us it has many things that we appreciate: a bit outside of town, silence, lots of nature and animals around (dogs & cat also inside), a small and cozy home. We also got along very well with Birgit and enjoyed spending time with her :)
Just know - as others have commented - this is not a hotel room where you are an anonymous guest without any interactions. You are a guest in the house, and most of the house is shared.
