I spent a week at Kelsey's and it was everything we we expected and more. The studio is spacious and very clean. The outdoor setup was really nice—we ended up spending a lot of time working/reading, etc. in the backyard.
As for location, you're away from the bustle but still very close to City Park and to the LODO/RiNo area to explore the bars, restaurants, and other fun activities the city has to offer. Would definitely recommend for both short and long stays.
