I visited Les Dunes Comodoro Hotel in July 2014 for one night stop Benidorm. The location is superb on the main beach front. You can walk straight to the sea from the hotel. We had a junior suite on the 20th floor which had plenty of room for 4 persons and wonderful views. The room was clean and air conditioned and the bed was very nice. Breakfast was OK in Spanish standards, maybe a bit too much British style for my taste. ONE NOTE! : The car park costs 40 € / night in the Hotel garage which is ridiculous.
