Sitting atop the crest of Beacon Hill, Fifteen Beacon offers some of the best views in Beantown. This 63-room hotel is housed in a Beaux Arts building from the early 1900s, and offers lavish, modern interiors, courtesy in-town Lexus service, gas fireplaces, custom Frette linens, and the cleverly-named and award-winning Mooo steakhouse. Have a furry friend traveling with you? It's dog-friendly, as well.
