We stayed at the Julien for a family wedding and had a great time. The best parts about this hotel are the location (very near the flat iron mountains) and the service. Every single staff person was nice, helpful and engaging. The only reason this is not a 5 star is that we had an issue with out A/C unit that took longer than it should have to fix over the course of our 3 night stay.
I would stay there again and would highly recommend this to anyone that would like to stay in style in Boulder.
