Excellent location. Nice and close to central Zürich. Good public transport. Limmat is nearby for a swim. Quiet at night.
Beware that you do have to like cats to stay here as the cats are very curious and do love the visitors place. So it does take some chasing around to keep your room cat free.
It's not great value for money, sharing the bathroom and kitchen with the host, however nor is any hotel in central Zürich. And for our short holiday trip it was excellent.
