Welcome in my apartment,
Ideal there is room for 2, but this can be expanded by placing mattresses in the living room. The apartment is conveniently placed 5 minutes walk to the train/tram/metro station Laan van Noi. From here it's 5 minutes to the Hague and a direct connection to Schiphol airport (30 min).
Within 10 at city center of the Hague, 15 minutes from the beach, and 10 minutes from the cozy Voorburg city center.
In short: central location to explore the NL and the Hague
