What was the best and worst hotels you ever stayed in?

Please describe what made them the best or worst.

Best hotel. Hilton or Hamilton (don’t remember) Large deluxe suite with living room, dining area, king bed and large jacuzzi tub
.
Worst: A little dive hotel in Madrid. Windows faced another building that was so close you could toss them a drink. The a/c felt more like a fan and you had to have your room card in the slot to make it work, so when you were out the room would heat up and barely got cool before you returned. The room was so small you had to single file to move around the room. (Though not the smallest room but the worst to sleep in) They didn’t offer laundry service and sucked at giving you directions to the nearest laundry mat.
