To be fair, the whole theme of Deadwood is 1880s, but I would like the room I sleep in to have a bit more modern security. The doors are interior doors like most people have on their home closets but they added two locks. One is a deadbolt which you don't get a key to (I assume security/maintenance has) so it only works from the inside, the other is an antique night latch which anyone can bypass from outside with a business card or screwdriver. Also, to properly open your door requires two hands simultaneously (one for the lock and one for the door knob), which sucks if you are carrying something. If you only have one hand, I guess you're SOL, but most things in Deadwood are not ADA compliant.
Beyond that major complaint, the rooms are plaster on lathe as was the style 100 years ago. They have a simple kitchenette with a microwave and mini fridge in case you have leftovers. The beds are clean although only double-size. The water pressure in the shower was almost nonexistent even though the sink faucets (separate hot & cold) both had good pressure. I'll probably spend another $20 and choose one of the other, newer hotels next time I'm in Deadwood.
