Very well situated flat, within walking distance of about everything you'd wanna visit in Amsterdam. The bedroom is quite comfy, we slept very well. Take note that the one(s) sleeping on the convertible couch will probably wake up quite often during the night, due to the noisy street.
Even if we didn't use it, the kitchen is very well equipped.
I would definitely recommend it for a week-end stay, and bring earplugs if you're sleeping on the couch :)
