This Doubletree checked all the boxes. The staff was friendly, breakfast was good, and the location can not be beat. Right on Helena's pedestrian mall, once you park--which is easier than some of the other reviews may have you believe--you don't need a car to explore the town or its myriad restaurants and breweries. I quite enjoyed the small balcony with full sliding door to get some fresh Montana air.
Yes, it is obvious this is an uplifted older hotel but Hilton did a great job of bringing it into the brand.
