My girlfriend and I had a great stay at Pauline's AirBnB. The apartment had an old-fashioned feel (e.g., the deep, freestanding bathtub), was equipped with everything we could need, and had a great amount of space given the location and price. Pauline was also friendly and responsive.
The location was very convenient for us - restaurants and a grocery store were within walking distance, and it was close enough to everything we wanted to do/see for us to mainly get around by renting the scooters from Lime or Lyft that are scattered around Denver (which I would highly recommend).
