Christine was a great host, and her son's place (which she looks after) worked well for my short stay in Zuerich.
It's 30 seconds from a Tram No. 3 stop (and then 10 minutes to the main station on that tram). It has a fully equipped kitchen, augmented by a few essentials (oil, bread, apples, coffee, milk) that Christine has made available to everybody! I would recommend the stay, if you want an easy place to stay in Zuerich.
There were four others in the house when I was there, but I only ever actually had a conversation with one person - so perhaps not the most sociable bunch ;) I would recommend bringing earplugs if you're in the downstairs room, as possible noise from the kitchen and one other room can disturb a night's sleep.
