I've been meaning to write about this hotel for a while. I stay in Mechelen often for business and of the "decent" hotels the Gulden Anker is my last choice.
The good stuff - reception is fine, the restaurant is EXCELLENT with beautifully prepared and presented food at very reasonable cost. Breakfast is OK, nothing special. Rooms are a decent size, well equipped and have internet access (pay).
The bad - The big problem with the hotel is the all pervading and strong smell of cigarette smoke - it is everywhere in the building (except, interestingly, the restaurant). Even in the non-smoking rooms, so strong is the smell that it seeps in to the room - yeuch!!! Maybe it is something to do with the design that the stairwell acts like a chimney disributing the smoke from the public areas through the building, maybe it is because the bearded guy at reception is a heavy smoker. I'm not sure, but if you don't like cigarette smoke don't stay here unless you have to (Mechelen hotel rooms are often at a premium and booking way in advance of your trip is a good tip).
