I went there from june 6 - 13 , 2014 with a group of friends. We had a great time.
Resort : immaculate, nice, set in the jungle.
Room: very clean, bar fully restocked and clean towel every day. Free in room wifi, but slow. It is a bit smaller than AKumal and Coba rooms. Nicer if have some more furniture as a desk, more drawers, long mirror in the room.
Food : very good food, fresh , a lot of variety. The bufffet is amazing. There are a la carte restaurants in Sian Ka'an and other complexes but we find the food in Sian Ka'an buffet better.
Beach: clean private beach with service to your chair. There is a bit of small rocks here and there. Better to have water shoes. Transportation by trolley from the hotel to Sian Ka'an the beach is frequent ( every 5 min ) and the drivers are nice , but if you go go from the hotel to Coba / Akumal beach, it will be long ( 15'- 20 ' waiting time ). More beautiful fishes in Coba beach.
Pool: very clean, nice and quiet among the nature. Amazing !
Entertaiment: live music every night, more shows in Tulum, Akumal and Coba complexes.
Overall, this is a beautiful 5 star resort with great food, great service, great staff . I would go back and I would recommend this hotel to anyone.
