The wife and I stayed at Kevin's house for 5 nights on an anniversary trip to Denver and the surrounding area. Kevin's house was perfectly situated in the RiNo district which is a very trendy area with great bars, restaurants, art murals, and shops all within a quick walk. This is a great location if you want to stay close to downtown Denver or the ball park.
The house itself is a small row house located near the intersection of 31st street and Larimer St with an alley in the back with one reserved parking spot. If you have more than one car you'll need to park one on the street out front. Access in and out of the house worked out just fine with the August app.
The inside was clean and exactly as described. It even had some surprisingly nice amenities such as the heated bidet, split shower heads, king size memory foam bed, Apple TV, and hot tub out back. We really enjoyed the private hot tub and the patio even though it would have been more enjoyable had the weather been warmer. We got good use of the hot tub, but would recommend bringing an extra towel or two.
Overall we highly recommend Kevin's house. Its perfect for couples to stay for vacation or work for a few days if want/need to be close to downtown Denver and within walking distance to a lot of good restaurants and bars.
