Stumbled upon this site while researching my trip to the Pacific NW at the end of May. Love how fresh, young and vibrant it is... especially when comparing to the standard hotel website. Looks like they still have a few kinks to work out and they do use a 3rd party reservation system, but overall I really like how out of the box it is for a hotel site.
Unfortunately, they're booked for the dates I'll be in Seattle :(
They have locations in Seattle, Portland, Palm Springs, and New York.
