I stayed at Karen's place for a month and a half when I was new to Zürich. She and Jakob (her son) made me feel at home in her house and gave me good tips and advice on settling in Zürich. We had interesting discussions over dinner with her friends or a cup of tea in the kitchen before bed-time :) Karen was also very accommodating in extending my stay for an extra week or two.
The room is big, the bed is very comfortable, and there was enough cupboard space for all my belongings. The neighbourhood is also a lovely leafy area that is very close to an amazing park (Rietberg). Very close to a bus stop and a 6-minute walk takes you to a tram stop with many options!
I would definitely recommend Karen's place for those looking to find their feet in Zürich before settling down somewhere more permanent!
