8.2/10 Very Good! (135 reviews)

Clean, large bedroom. Resort is old and patched up but ok. Great pool area with lots lounge chairs but pool closes at 7pm. Breakfast was great with a lot of savoury and sweet choices. Need car if staying there. Googlemaps led us through narrow sketchy road to get there but there's a better larger road to get there. And beware the highway exit, it is very narrow and easy to miss.
