Blanca and Chris were wonderful hosts! It was very easy to communicate with them, especially since our airline lost our luggage and we needed to arrange a delivery - they helped us out immensely! The location was absolutely wonderful - we never used public transportation once since almost everywhere we went was at most a 10-minute walk away :-)
Not a negative point - but I recommend this apartment for 1 person with more than one piece of luggage or 2 people with a total of two "checked-in" pieces of luggage. My husband and I each had a large suitcase and two small pieces, as we were traveling elsewhere after Zurich. So we were a bit tight on free space (There is a lift in the building as well). Also, we were unfamiliar with the keys/locks, as we're from the US, so make sure you figure that out. I'm glad my husband did, because he was on "key duty" during our stay :-)
Other than that, everything was great and we thoroughly enjoyed our stay in Zurich!
