Mark was an amazing host: fast response times and clear instructions. He was super friendly, proactive and considerate. My friends and I were without signal while climbing in Red Rocks, so we couldn't let Mark know an exact time we'd be needing the jacuzzi. But when we got back, we found out he had already warmed it up for us! It was great to be able to rinse off then hop right in.
Everything went smoothly, and his home is spacious, yet cozy. No one in my group of 15 people had any complaints.
