I had a great stay at this Air BnB, Heleen and Karel are great hosts.
It's a cosy small room with comfortable beds, a sink, everything was provided in the room (towels, tea, coffee, maps of Amsterdam, Wifi). The window is facing the back-gardens so the place is really quiet (I'm a light sleeper so this is important for me, i slept very well). Colorful private bathroom is nice and clean. Great neighborhood close to the city center, trams nearby.
I can highly recommend this Air BnB and definitely will try to stay there again when coming back to beautiful Amsterdam.
