I spent here one night recently. Upgraded from basic entry room to Deluxe Premier. However, except the family roms, all rooms have the same size. The differences are "better" view, higher floor and espresso machine. The rooms are fine for one person, but too small for more than one person for more than one night.
This hotel is one of the culprits providing no breakfast for Elites. Apparently it's (American?) Fairfield brand standard to provide breakfast for all guests regardless of status or membership, but this Fairfield is an exception. If you'd like to have full breakfast in the Bistro 879 you need to pay KWR 22,000 for adults (or KWR 11,000 for children 3 to 13). For welcome amenity you might choose btw. 500 points or drinks or toiletry options.
