Convenient & friendly
Waited until too late to find anything else at a good rate through Southwest. Stayed here 3 times before and I gave it a rotten review the 2nd time. Made sure I was in the Tower & high up and not in the Annex. No noise. Elevators worked very well. Room small with a king bed but only me so plenty of space. Yes, the bathroom is very tight and would be tough with 2 people trying to use it. Clean & bed comfortable. Staff very friendly and helpful. You can't beat the location - steps away from 16th street & the free bus, within walking distance of Convention Centre. 
Went for the Super Shuttle & couldn't find it. Man [aka limo pimp] told me "no more shuttle to hotel, you take taxi or this vehicle." Turned out to be a "limo" [SUV], waited for 3 other passengers as I refused to pay $55 one way. Should have dragged my luggage back into airport to info booth & asked. Instead of a 30 mins. trip, took NINETY minutes because 2 passengers dropped off in Cherry Creek, 14 miles from Sheraton. Man lied. Super Shuttle still running, leaves from different location because of major construction at airport.
