I want to divide the review into the space, Jack, and the area.
The space: Excellent spot that was extremely comfortable and well stocked. We stayed for two weeks, and the house had everything we needed to cook, to relax, to call home base for the time.
Jack: He was a timely communicator and very kind. We stayed longer than the average length of time and ran out of a couple necessities. Within the day, he brought us everything we needed. In addition, we had a couple of questions which he quickly and clearly addressed. He is an excellent host!
(not a review but worth noting) The area: The apartment was very close, only a few blocks, to a beautiful park and lake. There was a path that circles the lake and is great for a stroll or run. Edgewater Public Market is about 0.5 miles south of the apartment and is a fun food market that is worth checking out. There are lots of other nice spots in the area (and Jack recommended some others too).
I would happily stay at this place again the next time that I'm in Denver!
