We had a 10 nights stay in this really spacious, clean and beautiful apartment. We had basically everything we needed for our stay: enough towels, toiletry, tableware, pans, pots and so on. The private rooftop terrace is really nice even though the way up there is quite adventurous in the beginning (but still totally worth it, every evening). Leandro was very communicative and helpful at any point.
The location is a good starting point to different destinations, as there are tram and bus stops right around the corner as well as the train station Lan van Noi, which is a 15 minutes walk away. The beach can be reached easily by bus or bike. A grocery store, as well as really good restaurants, are in the near neighborhood.
If we came back to Den Haag someday, it'd again be this apartment, that's for sure!
