Paul is very friendly and communicative older active men. It was my pleasure to stay at his home and I enjoy tea offer :-)
As for my small room, there is bunk bed with 1 single on top and stretched double sofa bed at bottom with thinner mattress. The bed is not so long but as I am short it was not a problem.
As for Paul apartment (15min walk from Center and 30min from Station), there are really steep stairs from the street, it is very old (50 years maybe?) but with good Wifi internet connection, renovated smaller bathroom (just missed shower gel) with nice big bath (with jacuzzi nozzles) and very tiny toilet where your knees touches the door (broken knob/lever). Sadly the kitchen has seen its best many years ago and should be also renovated, not working dishwasher could be replaced with small built-in refrigerator which is now in living room.
In overall, I spent nice 3 days in The Hague in Paul apartment. It is maybe not for someone who likes everything perfect but is definitely worth it ;-)
