Regarding the chlorine smell in the room, and the statement that it was from the pool.
I just read Colorado Covid timeline and came to the conclusion that the state responded fast. Schools were closed on March 16, ski resorts and gyms, in March. Given this, I seriously doubt that the swimming pool in Broomfield, CO, stayed open in May as it would be a violation of Covid policies given that the gyms were closed at that time. If the hotel closed the pool, though, and pumped out the water, the smell of chlorine for 4 months in a room below would indicate serious violation of building codes, or leaks. Having stayed in multitude of hotels, and motels, and inns, in the country and all over the world, I never heard of such a situation, the smell of chlorine in a room above the pool. It would be interesting to see if the pool is even below the rooms, but if it is, as it sometimes happens, there is additional insulation.
P.S. read reviews about the inn on Travelocity and some on Hotels.com. Mostly, positive; people would mention slow room cleaning service. No one said a word about the smell.
