I have completely renovated the ground floor apartment in 2012. the result is lovely, but I am unable to enjoy it all the time due to extensive travel for work.
The large open plan kitchen leads into the dining area and wil allow you to either organise your own dinner party or just hangout at the long dining table.
Most of the furniture is either handcrafted woodwork from a Dutch woodcraft artisan or purchased in Dutch signature design shops.
The result is a simple but elegant apartment ready to accomodate a couple + child (if required 2 extra adult on the aerobed).
Most of the major musea of the Hague are within 5 minute walking distance and the neigbourhood where you will be staying is known for its relaxness and radiant international ambiance due to all the embassies that surround you.
Public transportation... what can isay, you are in holland, so you are surrounded by it. Ofcourse I do recommend to use the bike instead of tram/bus, so I have left you two bikes in the garden.
