Have stayed at the Corinthia on business several times now;- it's definitely one of my top ten hotels. Its a large modern building on the outskirts of Antwerp, though very easy to find from the main road. Rooms are well-equipped and comfortable, always spotlessly clean. I always appreciate the complementary glass of champagne on arrival - a nice, imaginative welcome.
The restaurant is very good too, well above normal hotel standards, though they can become over-stretched if a large group unexpectedly arrives. My only real complaint if I had one is that parking spaces are limited in the underground car park and that they don't yet accept AMEX.
