This was our third trip where we stayed in this apartment, which I think pretty much speaks for itself. You can guess we really like the location, host and facilities. The only minor change since last time is a dedicated WiFi for the apartment (fast) and a shower door in the bathroom (used to be open). Bed is still comfy, apartment still quiet, view still the best there is.
On a more serious note, this area of the Hague (Schilderswijk) used to be a bit rough but in the last few years it's become more and more renovated and crime has dropped dramatically. I wouldn't hesitate recommending that you walk to the city center instead of taking a tram now - it takes about 10 minutes and it's a straight shot along Zieken to the Spui.
