This hotel was disappointing so was Puerto Arista in general. The rooms were pricey especially since our room had a lizard, bugs and lots of ants. The room was small and the small smelly bathroom made it unpleasant in the hot afternoon/evening hours. The hotel was quiet on Thursday and Friday -- there were very few guests. Saturday and Sundays are more hectic as many people flock in. The small pool gets crowded on those days.
The hotel is one of the more pleasant-looking ones in Puerto Arista. The restuarant serves good, but overpriced food too. The service is slow -- it takes an hour or more to get food, regardless of what you order. You can watch the staff sit and chat while you wait to be served. They also never seem to have change for anything (this is a general problem in Chiapas). They claimed their credit card machine was not working when we were there in June/July. We even had trouble getting receipts after paying for everthing with cash (this was a problem we encountered all over Chiapas). Your meals are likely to be interrupted by peddlars selling food.
The beach was georgeous though. The waves do pound the shore and high tide greets early-morning swimmers. The sunsets are also quite pretty from the beach.
