My second stay at Marleen's (the last being 4 years ago when I came for the same conference). Lovely, clean apartment, close to World Forum and a short tram/bus ride from Den Haag city centre as well as the beach - as pictured and described. Marleen is ever so friendly and warm, I had a great stay and definitely happy to be back... (oh, and she also gives great tips on where to find rare local gins...)
