Train Stations always good; service can be spotty hit or miss esp if they know you are a drive by in and out type vs a local etc. I personally love the RLD's/train station areas. Some more options for indies,

Few FKK's there,just google them I don't venture to that area much went one time to see a former girl I knew from Hessen but was in a private flat. She's now in Darmstadt at Sharks which is out of your way.
Good luck, happy travels.
