We stayed at the Mercure Lille Centre Opera for a 2 night New Year break 30/12/11 - 1/1/11. It is a perfect central location right behind the opera house and you can't miss it with the 'Mercure' signs. Staff on reception so helpful, printed out guides of where to go and exact transport (metro) journey planners for the museums. Perfect for a stroll to the Grand Place literally a few steps away. Great 'continental' breakfast but actually had a few hot breakfast items and great cakes and cereals, enough to keep you going. The room (privelege, worth the extra money) was beautiful, massive bed, with a great view and lots of free soft drinks in the minibar. What stopped this from being a perfect review was a weird smell on the first evening after there had been a rain shower in Lille. It smelt of sewage in the corridor, which slowly filtered into our room. I complained down to reception but they couldnt do anything. Luckily it went in the morning, but just a forewarning if you're going in the winter / rain time!
Overall though I would recommend highly it was just a shame about the smell on the first night.
