The Hague (Den Haag) is a quaint city about an hour from Amsterdam. We stopped here on our way to Belgium and is one of my favorite cities. The streets are filled with great restaurants, people biking and a lot of life.
While there we stayed at the Hotel Des Indes, which is a Luxury Collection Hotel and it was absolutely beautiful. It is located in the heart of the city, walking distance to every place you want to go. The rooms were grand with beautiful views and the service was top notch.
If you plan to go to Amsterdam or Belgium I recommend stopping for a night in The Hague--you won't be disappointed.
