Sheraton Grand Seattle 
Zagat
Star Service
Zagat "A "great hotel for business travel", this "large", "classy" Downtown tower has "some of the largest conference spaces in town" and "beautiful", "well-appointed" rooms and suites (all with "heavenly" beds, and some with "peek-a-boo" views of Elliot Bay); though some grouse about "ridiculously expensive" parking, fans both on and off the clock applaud the "impressive" lobby, "excellent" service and "fantastic" fitness center and pool"
Star Service "The bi-level gym is also free to use, with exceptional views of town and the latest workout equipment"
