I haven't specifically been in the one on the Star but have been in a few of them. We enjoy it. Don't do it everyday but we pick a day or a morning and just relax. They're lovely padded lounge chairs, very attentive service and QUIET
As for pool, on most ships it's located at the front just above the spa pool so you're only a couple of steps away from that pool and it's two hot tubs. Island and Coral have a private pool at the back of the ship in the Sanctuary.
