Mark's place is comfortable and matches the online photos. Mark is a very responsive and accommodating host. The kitchen was well stocked so we were able to cook daily during our extended stay, and the apartment was spotless when we arrived.
Note that laundry on site is coin-operated and a very short walk from the condo in a separate building. Mark provides a starter supply of the basics (paper towels, soap, toilet paper, etc) and then you're requested to get more if needed. Cleaning is on your own for the duration of your stay.
The actual condo complex is more tired than we expected, but is quiet and we felt very safe. Grocery stores and other restaurants are close but not necessarily in walking distance.
We did have an issue with the neighbors smoking outside and the smell coming in through our open windows. This is something Mark is actively dealing with.
Mark's place was a good start to our new life in Denver.
