Barbara has an inviting home in a safe area of Munich easily accessible by public transportation. She does have a lot of art work and items she has collected throughout her apartment, but it is all very well organized and there is plenty of space for her airbnb guests.
While Barbara ' s expectations may come as a surprise to spme guests (being asked to use only one light in a room, being conservative about water use, etc.), she isn't asking anything unreasonable and her commitment to being environmentally conscious is admirable.
I was initially taken aback, for example, to find she'd entered my room while I was out to turn off the power strip, replace the note with wifi code to its designated spot and put my toothbrush in a mug. When I thought about it though, I made the mistake in not turning off the power strip in the first place and the other two were done with good intentions, I'm sure.
Barbara likes things a particular way and if you can adhere to her expectations you'll enjoy your stay very much!
