Located in Seattle s Historic Belltown neighborhood on 3rd and Battery, O2 is the contrast you ve been looking for. Five blocks away from the Seattle waterfront leaves you in the heart of it all with the option to retreat. Walk to catch a show at the speak-easy style Big Picture, or head to Vue Lounge to take a load off after a long work week. Breathe in the beauty of the Northwest on our Sky Garden Rooftop or find your balance in one of our yoga sanctuaries. This is the spa that you deserve, right in your own home.
