Marriott hotels are always up to good standards, but some are better than others. I recently stayed at Marriott Hotel Al Jaddaf in Dubai and must say this is the best Marriott hotel I have stayed so far and easily comparable with their upper JW Marriott-hotels.
What makes it better is the service and the beautiful contemporary rooms. Well-trained, professional staff in all areas of the hotel that are a level or two above your average Marriott hotel. The standard rooms even have rain shower and freestanding bathtubs, while you can find L’Occitane products in the suites. Comfortab
The location is not the best, but they operate a free shuttle to Dubai Mall making it rather nice to stay in a more quiet area of Dubai.
