Room in a shared flat

We're looking for a friendly, open-minded and sociable subtenant for October. We're Ella (25 F), Rebi (28 F) and Johannes (29 M). Ella and Rebi are both doing their master's (geology and computer science), and Johannes is doing a PhD (computer science). Since Johannes is travelling in October, we're looking for someone to take his room for a month.
Living together here is pretty relaxed, and we do a lot as a flatshare, whether that's cooking together, going swimming, or movie and board game nights :)
We care about keeping the place clean, but we're not super strict if the cleaning happens a couple of days late. The flat is very spacious with a great location close to the Limmat and your room will be completely furnished.
