I just spent the weekend for a wedding in the Hague. I stayed at Hotel De Beukenhof in Oegstgeest. It’s a very nice hotel combining charm, the building is old and very typically dutch, and design, every room is a suite appointed with B&O equipment and all kinds of amenities (our room even had a sauna). If you need to be near the Hague, it’s a great place to stay. The restaurant is also very good and even the service, not exactly a dutch forte, is excellent.
