Single room for rent - 2544 Bettlach

The room is not accessible from the outside; it must be accessed through the apartment. That's why I've described it as a shared room. Let's see if anyone is interested. I am a 55-year-old divorced man with a room available. I prefer women, younger or older, but I think younger women are more likely to be interested.
I'm still struggling to put a price on the room.
Because I don't know if we'll organize meals together, spend time together, or if a friendship might even develop.
But I think I'd like at least 500 francs per month for the room.
