If the temps are creeping up, but it's not quite enough of a scorcher to hit up an outdoor pool, Hotel Nikki is your spot. This downtown destination with an indoor pool offers an airy escape from the city. The filtered sunlight, warm water, and open architecture make this one a go-to — even on those awkwardly mild days. Pop into Anzu for a post-swim treat, and be sure to swing by with a pal cozying up here for entry.
Hotel Nikko, 222 Mason Street (between Ellis and O’Farrell steets); 415-394-1111.
