I had a very nice stay at the place. I was in town for a conference, and it is about a 12 minute walk from the convention center. It's also a couple blocks from a big supermarket and 10 minutes walk from the nearest train station. This was what I was looking for. It was nice to be able to have my "own" place to go back to every evening instead of being trapped in the conference hotel!
The house is really cool - it has nice design and architectural features that make it both quirky and fun. The downstairs bedroom is pretty small, and I chose to sleep in the loft. It's a steep ladder to get to the loft but I really liked the cozy/comfortable space. When I was in Denver, the temperature changed from 75 degrees and sunny one day to 10 degrees and snowstorm the next day, and the house was comfortable in both conditions.
The hosts were great. Check-in and check-out were easy and there was excellent communication. Overall, I'd highly recommend a stay here for your next visit to Denver.
