I have stayed at this Mercure previously and it was quite nice, comfortable and conveniently located. I usually do recommend this hotel. On this occasion, the experience was memorable but for different reasons.
Arriving in the afternoon, there was a line of customers waiting to be checked in, my wait was 25 minutes, it took far less time in passport control than check-in. On the second day, owing to what I later learned was a flood in another room, the water supply was cut off - no one knocked on the door to explain this and as the telephone did not work in the room, I could not inquire about this. My day began with limited ability to finish my morning routine, luckily there was a bottle of water but... overall not good!
The lamps all include dim, tinted bulbs and even with each lamp turned on, the lighting is poor, even in the bathroom.
The black-out curtains would have worked perfectly but, they did not fit the window completely so, there was outside light coming into the room either in the middle where the curtains did not meet or from both sides of the wall.
The TV remote was malfunctioning so there was no way to adjust the volume.
Unfortunately the 220V outlet did not allow for a standard shaver plug to work, it required an adaptor which most experienced travellers do take with them so at least I could use this.
Little things like this do add up and does affect the overall experience whether business or leisure, I will think twice about booking at this location again.
