I was looking for a place that allowed my group to easily explore the center city, and David's place delivers. There are many restaurants, bars and brew pubs within easy walking distance. The 16th St mall, with its free bus service is a block away. The baseball stadium, arena and football stadium are about 0.5, 1 and 1.5 miles respectively. And the train station is about 4 blocks, so if you are flying to Denver, it is a breeze to take the train from the airport and wall to the condo.
The condo itself is smallish, but still comfortable. The master bedroom is good size. The second bedroom is small. The third "bedroom" is an air mattress in the living room, which is not particularly comfortable or private and would take up too much room during the day, so four people is all that the place can comfortably hold.
Parking can be an issue, but David worked out a solution for us even though his spot was occupied. The staff at the building's front desk were very friendly and helpful, and made checking in very easy. David and I exchanged a number of messages, and he was always responsive.
