Can you recommend acommodations within walking distance?

I would stay at Magnolia Hotel Denver, a Tribute Portfolio Hotel. It's a very charming, well kept hotel.

We stayed at Sonesta, formerly Crown Plaza. It's 3 blocks to the Paramount. Nice enough place, great little restaurant for breakfast. Expensive to park but where isn't?

We started at The Curtis. It was a 12 min walk and that was with someone on oxygen. I have also stayed at The Sheraton.
