One of the last independent hotels in Boston, the Colonnade Hotel recently poured $20 million into a gut renovation of its rooms and public spaces, giving its once-tired interior a glossy new look—the lobby’s done up with black woods, gleaming tile and detailed molding, while the guest rooms are dressed in soothing neutrals. Guests might not notice new little touches like extra outlets for charging up iPods and laptops, or the air conditioning that senses when you’ve entered the room. But they’re there, and they make a stay here very comfortable. For all the flashy upgrades, the hotel’s greatest asset has remained untouched: On hot summer days, the glistening rooftop pool teems with sun worshippers. Rooftop renovations are in the works, but in the meantime, it’s still the city’s best spot to catch some rays.

The Colonnade Hotel Amenities:

• 285 rooms. Wireless Internet access. Restaurant, bar. Fitness center. Pool. Business center.
