This indoor-outdoor rooftop complex, lined with quartz walls, has fire pits that welcome you into the enclosed space. Hotel visitors are assigned a 24/7 personal assistant who can reserve deck chairs, fetch sunscreen, deliver cocktails and food (try the applewood-smoked mozzarella sticks), and even adjust the temperature. Once you’ve toweled off, the same helper can book ballet tickets or a shopping trip with Capella’s resident fashion stylist.
GET ACCESS: Exclusively for hotel guests, so stay the night, make a friend on the inside, or beg.
