We stayed at this hotel in late August, 2007.
Back in 1900, if it was hot outside, it was hot inside. More than a hundred years later at the Hotel Colorado, still without air conditioning, not much has changed. If it's hot outside, it will be hot inside.
The hotel is quite close to I76 and a main transcontinental rail line, so open windows make for a noisy night.
The staff was slow to clean up debris from room service that was left in the hall.
Too much money for historic charm.
