We were visiting friends in Angola and came here for the weekend. At around $160 USD for a night was extremely steep, but not out of line compared to Luanda. The rooms are small cabins and are very comfortable, they have a small fridge and AC. However no hot water in the shower is unfortunate. Take a shower in the evening as the water is a bit warmer. They have a nice little beach with chairs for rent where we spent most of our time. It also included a really nice breakfast.
We also had dinner at the restaurant which had a great selection of seafood. The food was really good.
