Mercure Bangkok Siam is a hotel with rooms in the Siam area of Bangkok, directly in front of BTS National Stadium station and across from Siam Paragon and Mahboonkrong. A convenience store is on the first floor, the lobby is on the ninth floor, and a swimming pool is on the rooftop. Because the front desk is on the ninth floor, guests take one elevator from the first to the ninth floor and switch to another for the guest floors. The in-room refrigerator does not keep water cold well.
