Exchange 3-room apartment with balcony in Zurich, District 6

Hey! I offer a charming old apartment in lively Zurich, District 6. It has a beautiful balcony with a view of greenery and a garden for shared use. It is a city apartment, which means you must live here with at least two people and not earn too much. The apartment has a shower instead of a bath. I am looking for a smaller accommodation in Zurich where I can live alone with at least 2 rooms, with a rent of a maximum of 1200 CHF.
