This just in under “places you thought only existed in your imagination”: the Library Hotel in NYC, just 0.3km from the New York Public Library. Aside from just being a really beautiful- looking, fancy boutique hotel ($300/ night fancy!), this hotel has the BEST system for floor and room designation.
Each floor of the hotel is devoted to a category of the Dewey Decimal system (!) and each room is themed as a different sub-category! So Room 1100.002 is floor 11 (Philosophy), Ethics room. And room 500.005 is Floor 5 (Science), Dinosaur room!
I also have a sneaking suspicion that the hotel bar may have cocktails with fun literary names.
Be still my heart.
