Tidy, good place to start a trip into the old town / the center of the city, sufficient parking possibilities, can be reached easily from south by car, but the quality of mattress/bed is not satisfying (head end of the bed is soft, the place for the pelvis is like stone, also the double bed is small and has a hollow in the mid - like a single bed usually has it after many years). The pillows were like one rectangle piece of foam material, you can't crush it, and so you can't find a pleasant position for the head.
Last but not least the service personnel while having breakfast is rude, just because the coffee machine was out of milk (not signalling this for the user with a warning).
While Haarlem is really a nice place also for sightseeing, I am not sure to visit Haarlem again after this expirience.
