We recently stayed here for 2 nights, the 1st night was paid with cash (about 200USD) and the 2nd night with 45K Hilton points (very good value). It is about 2 hours from Hanoi by car/grab, we paid 50USD. As a diamond, we got an upgrade from an Oasis deluxe to a Tam Coc Villa which was very much appreciated. The rate of the villa is 500 USD per night. There are no TVs in the room but you can request for it, minibar is free which is 1 Coke and 1 Schweppes, 2 bottes of water. There is a Nespresso machine with 2 capsules and 3 teabags. The heated pool was fantastic with views of the mountains and limestone cliffs. The breakfast buffet was impressive, as expected from a 5-star hotel. They also have a free buggy ride from the hotel to Tram Coc boat station which you can book from the app. Perfect if you want to have dinner in town, just like we did or if you want to do the boat trips, they caves are smaller though as per the staff so we did the one in Trang An which is a UNESCO Heritage Site. The staff were all friendly, and with the upgrade we got, it was one of the best hotels we have stayed at.
