The apartment is awsome and excellent value, the pictures are completely accurate. It is actually even better because there is a also a shower in the bathroom in addition to the bathtub. I was able to get the keys to the apartment although I arrived rather late and that was so very helpful. The written instructions in the appartment were very clear and they were full of useful tips. The market in Ten Kateenstraat is a great for a morning stroll on your way to whatever you have to do (conference in my case). The spaghetteria around the corner is very good.
Book it if you can, but hopefully not when I am back in Amsterdam!
