Klaartje's house is really a perfect place. Bed is confortable, everything is clean and there is many attentions : tea, Coffee, chocolate and marmelade for breakfast, périodiques protections in toilets in case, soap, etc.
She also has been good advisor about where eating arround (and I add "meatless" to try ). Don't hesite to go there. The last think I could had regret IS that I was looking for a place whith kitchen, but even that was not a real problem because there is a fridge there and plates, classes, etc.
And every thing is not far away. You Can go go city center in 15 min with tram and even Can walk.
