This is a no frills place with basic facilities and decor. It’s fine for a work trip. Rooms are small, the bed is right there when you open the door. Clean bathroom and Nuxe hand wash is nice. Hardly any English speaking channels on the TV work, most have no reception. Very friendly Reception staff. Tip: When you get your room, ask if it’s next to a fire exit. Rm 37 is right next to one banging all the time. Message to mgt:paper cups next to kettle have a label saying “contains plastic” – come on Mercure, you need a green policy! The hotel is walking distance to Châtillon Metro
