The Westin Seattle 
Gayot
Oyster
Star Service
Gayot "A prime location on the edge of downtown and hip Belltown puts the hotel close to the convention center, as well as happening restaurants and hot bars"
Oyster "Simple, elegant rooms have floor-to-ceiling windows with cityscape views, and one- and two-bedroom suites offer wet bars and some have conference tables"
Star Service "Connecting rooms are in abundance, but disappointingly, there is no club level or lounge here like at the Hilton nearby"
