Fantastic location, big room, no stairs for luggage, walking distance to everything. Karin was lovely and had a great little map and info book of things to do in Amsterdam.
Things to be aware of: the noise from the floorboards above is quite loud, so if you are planning on sleeping in past 9am, probably not the place for you. Also, there is no lock to your room, only the front door of the house. We weren't worried so much by this, but it's worth noting if it's something you would want.
Would recommend if you want a great location and aren't bothered about morning noise.
