Unbeatable location: 10m to Bahnhofstrasse by train, big grocery shop around the corner, very nice and quite place.
Abundance of living and storage space . Very pleasant host - smooth check-in, very responsive, fluent English, local tips, etc.
A few insignificant things like the kitchenware could have beem renewed as pans are worn off and a little bit more meticulous check-out cleaning would be much appreciated.
Overal impression: Highly recommend!
