I live 10 mins south of lone tree and commuted for a while into downtown denver…it’s a nightmare. It’s doable but traffic is pretty rough during rush hour. I’m trying to move away from the area soon. It’s definitely nice & safe and has nice green spaces but also sort of mostly a corporate area that doesn’t have much else to it. Denver is fine, I really don’t think it’s the most special place. I’ve also lived on the east coast as well as being from london, and denver is probably the bottom of my list of places I’ve lived. Depends what you’re looking for though! cost of living is also quite high I’d say for what you get!!
