Mary (aka "Buffy") is great. I stayed with her for a week because I was traveling for work and I chose her place because needed to go to a conference center nearby daily.
She was excellent with communication and greeted me when I arrived at her door. After a tour of her cozy home, she took extra care to make sure that I knew how to get around the area, where my conference would take place, and interesting things nearby. Also, she had baked pumpkin bread to share! So sweet. There's a grocery store nearby, too, and she has empty space in the fridge to allow you to store food.
The room and bathroom were both very nice and clean. The bedroom had a nice view of the street. The area around her home is very quiet, which is nice. It's about a ten to fifteen-minute drive away from downtown; unfortunately, there aren't many public transportation options nearby.
It was great staying with her, and I'd do it again if I ever find myself in Denver again.
