I agree with the above 2 posters. There isn't any truely luxurious hotels near the airport. Take the short train ride to downtown. The W hotel is value for money (relatively speaking) which has grown on me after my recent stays. Or if you willing to pay a bit more, you can push the envelope and book a club room/suite at the Four Seasons. Both hotels are located directly above the airport express train station, very convenient and accessible.
