Jon's home is absolutely lovely, and if you're even considering it you should just go ahead and contact him to book it. The location is in an up and coming neighborhood and it's super walkable, with plenty of stuff around to suit pretty much anyone. Jon was away skiing the weekend we were in town, but we got to say hi and bye, and got a ton of recommendations from him. Then when we couldn't remember one of them the next day, he replied to my question from the slopes. Plus it doesn't hurt that Denver is lovely in general.
Again, if this place looks like it might work for you, just book it and you won't be disappointed.
