I thoroughly enjoyed my stay in this lovely apartment. It is beautifully refinished and comfortable, and stays cool even in the 100-degree heat that Denver was blessed with during my stay. The neighborhood is casual, residential, and populated by a variety of folks, mostly aged 20- to 40-something, who can be seen walking dogs, pushing strollers, and hanging out at restaurants and parks. Whole Foods is two blocks to the west and a King Sooper is two blocks south, making it easy to walk for groceries. WaxTrax Records is a walkable few blocks to the northwest, and a few blocks beyond that gets you to the Civic Center / Library / Art Museum area in lower downtown. There is also of course Cheesman Park, just a few blocks east.
The family who own the apartment live upstairs; as a guest you may encounter them in the back yard and hear them inside the house, but the noise was never overly distracting and they never intruded on my privacy. There is a certain amount of traffic noise audible from inside the apartment (only extra-loud cars and motorcycles, for the most part) and one night the next-door neighbors had a loud evening party in their back yard, but this is of course to be expected living in close quarters in a large city. Even with these occasional noises, my three days in this apartment were far quieter and more peaceful than my previous stays in downtown Denver hotels. I highly recommend this apartment.
The only potential drawback is the low ceiling height. I am 6' 3" and there were a couple of spots where my head nearly (but didn't) hit the drop ceiling. If you are 6' 4" or taller, you'll have to duck your head between the living area and the bedroom. 6' 6" or taller, this is not the rental for you. :)
I'll definitely try to book this apartment again next time I'm in Denver! I liked it very much.
