Apartment for rent - 8008 Zürich

I am looking to exchange my 1 room apartment 4 min away from stadelhofen train station and close to the lake. The apartment is at the ground floor and very central only 10min from paradeplatz. I am looking for an apartment of 1.5 to 2.5 rooms under 1800 chf in the center or near the center close to the train station.
