I stayed at Steffi's place for a month when I first moved to Zurich and really loved my stay! The location is great – I hardly used any public transportation as most places were within walking distance. The room is spacious with a comfy bed, and the kitchen is well-equipped if you want to cook meals at home. Communication with Steffi was also super easy and she was quick to respond to any questions I had!
There's a bar downstairs that could sometimes be a bit noisy at the weekends, but a pair of earplugs sorted me out. Would highly recommend :)
