Perfectly situated in the heart of Ghent, the Marriott is a comfortable and luxurious stay. Primarily targeting the business traveler, the hotel is quite pricy (20€ per person for breakfast), but with an array of alternative cafés and restaurants in the immediate vicinity, this is not really a problem. Friendly staff and reception.
Room comfort is excellent and amenities as expected.
If you can find a good offer through Hotels.com, then this is certainly worth the stay.
Car parking is about 3 times as expensive with the hotel garage than using any of the multitude of public car parks in the city center (underground garages).
