Even if you haven't heard of Escher or know his work this is a "must-do" exhibition. The whole exhibition is well organised and displayed tastefully throughout the rooms of the old palace without seeming to be out of place and enabling one to view details about the palace as well. Lots to keep both young and old entertained throughout, especially in the interaction section on the top floor - unfortunately the museum closed at 5:00 pm otherwise we would probably still be there!! The facilities such as the cloakroom, luggage store (as for all museums large bags must be stored in free lockers before viewing the exhibition) all in excellent condition. There is a audio tour that one could download for free onto your phone but we didn't do this as the process was time consuming and required too much personal information. But an audio tour wasn't actually required since all the exhibits & works had good descriptive information in both English & Dutch
