This is a large company that offers professional service. The staff at City Stay were responsive to all types of questions (how to use the washing machine, telephone, where to shop, etc). I especially valued the service of Paula who met me at the apartment. The Lindenstrasse apartment is older and the bathroom really needs to be refurbished. It is hard to shampoo your hair and hold the shower the head at the same time. The flooring in the kitchen needs to be replaced. Apparently, this will take place in Spring 2016. The bedroom was clean and comfortable. As stated by others it is important to remember this is more of a hotel than someone's apartment- therefore you need to buy everything you need (soap, sponge for dishes, oil for cooking, etc.). I will return to Zurich in a few months and will be happy to use the services of City Stay again.
