The RockHouse was a perfect house for us during our stay in Denver. For sake of context, we were 3 adults (my wife, me, and my mother) and 2 children (2.5/4.5).
Location - super easy access to I-70 so getting there from the airport was a breeze and for our many trips around the city we were always close to the highway which made things convenient. It's also on the west side of town so you can avoid some of the downtown traffic (esp if you are doing things out toward the mountains). The actual street the house is on was quiet, felt safe and plenty of on street parking. We felt like we were at most a 20 min drive to everything we'd want to do in the city and many of the key things (gas, groceries, good food) were more like 5 mins away most. There are 2 parks nearby as well, not short walks but you could walk there if you wanted.
House - was perfect mix between having character and feeling like someone lived there and being empty enough that it didn't feel like you were crashing at a strangers house while they were away. The house had just about everything that we needed and when we asked for some minor items (e.g. extra nightlights for the hallway since we have kids) the owner was super responsive and helpful.
We loved our trip to Denver and when we go back we hope to stay here again!
