A great place to stay. Communication was smooth, the building easy to find, check in was straightforward, and the apartment exactly as pictured and described. The neighborhood is really fun, with all sorts of shops and restaurants, and the view of the Limmat is to die for. It's a quick walk across the river to the Hbf, and nearby Bahnhofstraße not only has all the stores as expected, but has also little alleys that go off at intriguing angles with amazing architecture and shops that are even more charming than the big names on the big street.
As others have noted, the ceilings in the apartment are somewhat low, so if you're over 6' you have to be somewhat mindful. Also, the shower is enclosed only on 3 sides, and one of those sides is a panel that is only chest-high, so if you're tall with long hair, it's hard to wash your hair without getting water on the floor. But if you and your hair are shorter it shouldn't be a problem.
