Though a serious business hotel, the 511-room Longement (formerly the Regent) has plenty of charm. Rooms have sleek, generous work spaces, pillowtop beds (where you'll find a mini-cheesecake at turndown), and suite showers with floor-to-ceiling glass windows overlooking the Puxi district. The young English-speaking staff are thoroughly professional, and there's a tennis court, a lap pool, and a spa with a Vichy shower. Sunday brunch is a global culinary tour, with choices ranging from Peking duck and sashimi to chicken and mashed potatoes. For a portable lunch, Tong's deli counter, a chic little eatery, does great takeaway.
