Better Than You'll Expect
The Sheraton Denver Downtown Hotel is expansive. It's mainly a conference hotel, and because of their large inventory of rooms, rates for this hotel are relatively low or at least better than average in comparison to other Denver properties. We booked on Hotwire and paid $89 for our Saturday evening stay.
We parked in the garage which is $24 night, which is about average for a Downtown Denver Hotel. Since we were only there for one night we had light luggage and didn't need to use the valet services, or a Bellman. Check-in was very efficient and the Front Desk Agent who helped us was very professional and courteous. He put us on the executive level which is the 16TH floor in the Tower portion of the hotel, which is a short haul from check-in. If you have a good amount of luggage, a Bellman will serve you well, as the hotel is quite large.
The room we checked into had one king bed, and was a bit small. However the furniture was situated well, and the bathroom had plenty of counter space. Our particular room overlooked the city and mountains and was situated above 16TH and Court. The view was nice, but the room was a bit loud. We could overhear the band playing at Katie Mullins, The Sheraton's resident bar and restaurant until about 1:30am. This was not a huge deal for us, but if you are waking early the following morning you may need to specifically ask for a quite room at check in. 
All in all the Sheraton Downtown Denver is a good hotel, and actually a great one for the price we paid. The location is great for anyone traveling on business and working Downtown Denver, or for anyone visiting the city that wants to be close to shops and restaurants. Once you step out of the hotel you are literally on Denver's 16TH street mall, and only a stone’s throw away from the free mall shuttle. 
The only con's for me were the noise level in my room, and some may not like the fact that the hotel is HUGE. This is not a quaint boutique hotel by any means. However the rooms are modern, clean, well adorned, and the location is great. I'd definitely stay here again.
