I know someone who has a room available in a 2 person WG / shared appartment, with shared living-room, kitchen and bathroom, on Nordstrasse, two stops from Zurich HB.
Top floor, balcony with evening sun, sharing with a male, 30's.
Rent: CHF 914 + ca.CHF 50 bills.
Very good for the Letten, Langstrasse, Schaffhauserplatz, ETH etc.
Send me a private mail with a telephone number to arrange a viewing.
