For location and ease of travel, this is my go-to for hotels in Denver near the Union Station. The price is very competitive, and you are within a block of 16th street mall. Rooms are totally fine, and the access to the business floor is worth it. Do be aware there WILL be conventioneers here, obviously, but what a hoot to see all the comic book heroes in full costume bustling around last month or so. I needed a fan, as I am a "hot sleeper" and the staff was very accommodating.
