I really enjoyed my visit to the Kijk-Kubus. It is just one flat, which contains a open plan bedroom and study, as well as an open plan kitchen and living area. There is also a upstairs room in the "attic" that has a collection of Cactuses. The whole thing is deceptively spacious.
This isn't going to be a very long experience, probably a maximum of 15-20 at a push. There is a chess museum nearby and a hostel. Well worth a visit here, especially if you go to the Oudehaven, which has some very nice harbour side Cafés.
The Kijk-Kubus needs a bit of TLC as it is starting to show signs of wear and tear, this put me off giving it five stars.
