Stayed there with my husband and two kids while my my husband attended conference for a couple days. Service was Ritz Carlton level!! The location was great, we were able to walk around to most locations. Concierge was usually very helpful. I liked the fresh fruit and constant availability of water bottles - such an inexpensive way for them to add value. The doormen were always so helpful. My son left his jacket in the car and they went to get it from the valeted car for us.
Would definitely stay there again if we are in Boulder!!
