It has been a while since our stay, but we enjoyed Entre Cielos quite a lot and picked it over Cavas on that trip since we didn't want to pay Cavas's crazy high Christmas/New Years rates. The design is all concrete and bathrooms are generally open to the room, but if you like clean modern design, it is a great place. Service was quite good and we really enjoyed the spa and pool. The restaurant was quite lovely as well. You won't go wrong but service is not up to an Aman level if that is what you are looking for.
