Away from the city centre (but next door to Google's European headquarters), this hip boutique hotel in a renovated brewery abounds in seductive features, including a stupendous rooftop thermal pool, Thermalbad & Spa Zürich and a fanciful library-lounge, filled floor to ceiling with 30,000 books purchased from a local antiquarian. Spacious rooms sport slick, urban-cool decor (including the odd beanbag chair).
From the Hauptbahnhof, take tram 13 to Enge and walk five minutes' west.
