Oyster "Features include a large gym and indoor pool, several bars, and a farm-to-table restaurant"
Gayot "Avenue One serves fresh contemporary cuisine in an airy dining room and welcoming lobby lounge"
Zagat "The location of this 22-story chain outpost ("steps from the T and in the heart of Downtown") "makes it a winner" for business travelers and sightseers who appreciate its "clean and very stylish" rooms, "spectacular" views of the city and harbor, and "attentive, personable" staffers; guests can grab cocktails at the roof deck lounge or enjoy a "great meal" at restaurant Avenue One before a show at nearby theaters"
Star Service "During the renovation, the premium-level rooms were paved over; there is no longer a club floor with lounge access or privileged perks"
Star Service "Seating is in the split-level lobby lounge with its harbor backdrop, antique prints, granite tables, TVs and excellent harbor sweeps"
