Very small rooms, totally over-priced and staff that were particularly unhelpful. As a Marriot Bonvoy Titanium Elite member I thought they might be a little more flexible, but clearly they had no interest in providing service. I assume that with all the medical tourism business they don't need to bother with other guests. Never staying there again - do not book this hotel unless you have no other option.

Where do I start with this place. Amenities are ok but room was way smaller than advertised dimensions given. During check in, would not give points to my Marriott Bonvoy membership due to it being purchased through a third party. Points should be offered regardless. Next my bidet stopped working and they sent maintenance up to "fix". Nothing was repaired and not even a follow up call to let me know that it couldn't be repaired. That issue alone should warrant a room change. It's a property that was acquired by Marriott but should have done more research into quality before the acquisition
