Welpen-starter-set - WG Zimmer, WG gesucht & Untermiete Kleinanzeigen in Schaffhausen Welpen-starter-set

Hello everyone! I'm looking for a room in Schaffhausen for 2–4 nights per week, as I will start working there in a hybrid job and would like to stay overnight a few times each week. Currently I live in Bern with my partner. Does anyone by chance have a spare room or know know of options other than Airbnb or Booking.com, like private rentals or online marketplaces where I could find an affordable room?
