More problems than I care to explain. It is really beautiful to look at and with a little maintenance could be fabulous but it didn't provided the services it said it would: no pick-up from the train station, no shuttle within the area, no currency exchange, poor internet, their 2 restaurants are really two menus one in Vietnamese, one in English, no separate cafe, etc. Also there were frequent power outages and bugs and lizards in the room. When we went to settle the bill they couldn't use my credit card because the power was out and instead they just started to write the card info down on a random piece of paper, I was not ok with that, and it took 40 minutes to come to a solution because they barely spoke English (and didn't speak French, or Spanish, or Mandarin, or even charades- I can communicate fluently in French and conversationally in the others).
Though it appeared that the rules and their willingness to be helpful changed for their Vietnamese guests. So if you speak Vietnamese your experience will probably be very different.
The good things- the beach and pool were beautiful, peaceful and we frequently felt like we were the only ones at the resort, and the food from their restaurant was very good.
I'm a seasoned traveler who is easy to please and gave close to perfect scores on my reviews of the other four hotels we stayed at during this trip.
