I'm so afraid that my landlord (a big company) will use ANY excuse to rob me of my deposit when I move out... lol, even though I'm a member of Mieterverein.

The same landlord whose workers outright forgot to install the water heater in the kitchen the day I got the flat, and __painted shut__ the bathroom window. LMAO.

Though I can only second this -- use transparent fiber and be creative in where you route it -- and nobody will be able to tell you did something 'naughty' in your rental.
