Stayed here Mid Aug. Emailed the hotel a week before my trip and they confirmed that they upgraded me to a corner studio (am a titanium member). Think I was lucky occupancy rates are not too high when I was there. Service is really top notch and warm. I last stayed here 5 years back and I feel that the service is even better now, Rooms are definitely slightly dated and bed is a little too firm for my liking but rooms are still very comfortable.

Plat and Titanium members used to be able to have breakfast at the lounge and main restaurant but elite members can only have breakfast at the lounge now. Food and drinks selection for both evenings and mornings are very good and definitely better than pre covid. Will highly recommend the hotel if you are looking for a Marriott hotel around the Siam area. The only drawback is traffic so be prepared to walk, take the sky train or take a motor bike if you want to get around efficiently.
