It's a room in which doctors or nurses change your dressing after a surgery (sometimes you can go back home a few days after the surgery but you have to come back to have your dressing (important ones) changed.
It's true that in a hospital some people may say post-op as a noun synonomous for recovery room, Embonpoint, but the adjective post-op/post-operative is a broader term, at least in the hospital where I worked. See here.Post-op is another name for "recovery room" above. .
