Best of Boston

2013 Best Boutique Hotel

Nine Zero

Hip enough for Justin Bieber and Lady Gaga, yet sophisticated enough to attract the likes of Bill Clinton, Nine Zero treats all its guests like celebrities—even the penguins en route to the San Diego Zoo that it accommodated in 2007. With daily wine hours, pet-friendly services, and charming themed suites (including the presidential Cloud Nine), we give Nine Zero a clear 10. Book the Skyline View rooms and your loaner iPad will come preloaded with tourist tips, a music library, even retail-therapy apps.
