Rik has great communication from the get go and feels like an old friend before you even meet him. His place couldn't be more convenient - it's located in the heart of The Hague's central district, just around the corner from the tram stop and the bustling Grote Markt. Every store and restaurant you could want is in easy walking distance. Basically, if you like a convenient central location in an active cosmopolitan city, I don't think you'll find better than Rik's place in terms of location and value.
A couple of tips:
King Falafel is literally across the street and has great (and freshly made to order) cheap eats.
The Mauritshuis is a short walk away, which is one of the best smaller collection museums in the world (specializing in Dutch Golden Age paintings).
The Hague is great home base for doing day trips to nearby cities like Delft (a 10 minute train ride), Rotterdam, Leiden, or even Amsterdam.
Finally, a big thanks to Rik for being a great host.
