"A Thermal Spa with Stellar Views Over the past few years, Zurich’s Hürlimann area—the site of what once was Switzerland’s largest brewery—has transformed into the home of Google Zurich , a complex of shops, and this stunning spa built into the former brewery’s hundred-year-old stone vaults. Its crowning touch: a heated rooftop pool with stellar views overlooking the city. For an extra dose of pampering, book a room at the adjoining B2 Boutique Hotel + Spa."
