I had a one night stay in Boulder and chose this RI as there aren't too many chain hotels in Boulder. I made a great choice as the staff was friendly and helpful, the room was clean and spacious, and the location convenient. The hotel is located off a highway, in a quiet industrial park. The famous Pearl Street was a 10 minute drive away, and the Celestial Seasonings factory tour (highly recommend) also a 10 minute drive.
The lady at check-in was friendly and helpful and even pulled out a free coupon for a box of tea for us when we told her we were going to the Celestial Seasonings tour. She asked for our room preference and gave us a great room. I didn't hear a train whistle, but it's possible the train didn't run that day, or we were out of the room at the time. The room is large, with a couch and flat screen TV, full kitchen, and a combo table/desk. The only strange item was how the bathroom is set up. The vanity is outside the bathroom and is relatively large, but the bathroom itself is small and cramped. Be aware that the rooms are in separate buildings, so you must go outside for vending/pool/fitness center which are located in the main building. I lived this arrangement as I felt like the room was a mini apt and didn't hear any neighbors, but others may feel differently. Overall, I liked this hotel and would stay here again should I visit Boulder.
