We were not happy with this place in terms of comfort and cleanliness.
The sofa bed was barely worth the name. The mattress of the double bed was hardly better. The place was quite shabby and seemed hastily cleaned. We can deal with that, but finding an old tube of lube underneath the bedding (implying that it had not been changed after the previous guest) is simply unacceptable.
The cookware was dingy and unappealing to use.
Some basic hospitality gestures, such as a card with the WiFi code, were missing. Not having mobile data in Switzerland, this demanded more creativity than we would have liked to exert after an eight hour drive. That being said Day was always super quick to respond and very helpful and communicative. For that reason, I wish I did not have to write such a harsh review, but for this price (which may perhaps be low for Zürich standards, but to us it wasn't), and due to the positive reviews, we had expected the bar to be higher.
