Ian's house is a quirky old Victorian in Denver's Congress Park neighborhood. He has a great setup and my stay was very pleasant so I would happily stay there again.
If there were any nits to pick, they mostly have to do with the age of the house. There are limited outlets in the bedroom with none that I noticed near the desk, so you should pack a splitter and possibly an extension cable. The shower is positioned in an awkward place for tall people but with a little mindfulness it wasn't an issue. There's also maybe ten or fifteen minutes' worth of hot water so plan to keep your showers on the shorter side.
All that said, there are far more positives. The furniture is all very cozy, and there's a comfortable bed and desk in the room I was assigned. The kitchen is spacious and well-equipped. There's a washer and dryer and even a clothesline in the backyard. The neighborhood is close to all the great aspects of Denver but far enough that it remains peaceful and quiet. A ten minute drive or twenty minute bike ride will get you just about anywhere you'd want to be in town.
