I don't know if you're still looking, but I am moving out of my 1 1/2 room, 55sqm, ground floor apartment in kreis 4. The apartment has all the necessary furniture and dishes for one or two people.
The apartment is available for 6 months starting on June 1st. After 6 months the apartment will be available on a month to month basis. It's close to public transport and the Zürich HB.
