I enjoyed my time in the castle immensely - this is certainly one of my favorite AirBnB listings I've ever stayed at, and every aspect of this was above and beyond a standard AirBnB experience. If you get a chance, spend some time chatting with Ed about the process of remodeling and modernizing the castle; Ed is a gem :)
The most comfortable bed I can remember at a hotel or AirBnB; the neighborhood is walkable and Lime scooter-able (lots of people in this neighborhood use electric scooters to get around); the space itself is elegant and *very* spacious, and there are so many thoughtful touches that I don't even know where I'd begin in describing them all - I have already recommended the castle to half a dozen potential visitors to Colorado, and I do hope to be back myself at some point!
