This is a cute little apartment for a very reasonable price only a 10 minute tram ride from the central train station. It's not located in the very center but it's definitely central enough. The apartment is located on the top floor of a rather dated office building, which may not look exactly charming. But the apartment itself is very nice, clean, well-kept and well decorated. The owner is friendly, she communicates via e-mail (I did not meet her) and the check-in is very simple. I can absolutely recommend this apartment, the price is hard to beat for Zurich.
