We did stay at Azulik a couple of years ago. It has a nude beach and we were nude on the balcony of the room. Azulik can be ridiculously expensive for what you get, but if you keep an eye out, it appears on Sky Auction every now and then and you can get a room for about $80 per night. It's not one of the fancy rooms and there's no ocean view, but the jungle view was very nice and we had a great time.
