Lovely and clean, nice people, nice food, weather not great. Leiden is a lovely town and well worth a visit, but we didn't enjoy Amsterdam and wouldn't bother going again! The beach at Wassenaar was nice and clean.
wassenar and duinrel is the perfect park for young and elder children alike. Adults can also have lots of fun. Liden is close by as Den Hague and Amsterdam. Having a car makes it easy to visit near by towns and cities
