Everything was as described: easily accessible from every point in town, very nice house, friendly reception and recommendations for restaurants, clean an comfortable room (small, but absolutely sufficient). Sharing a bathroom with another guest was no problem. We slept very well except for the little detail that there was quite a loud noise from a boiler located in the wall next to our room. It turned off at about ten at night but unfortunately turned back on at quarter to five, keeping us awake for some time. After we asked, Irene's husband changed the time setting of the boiler, but it still started before seven - not our usual holiday wake up time.
Overall, the experience was good though and we really enjoyed Den Haag!
