My husband and teenage daughter stayed in Marion's place for one night while visiting Amsterdam for a concert. This is their review: "Marion's place is simple, clean and comfortable. Two single beds, a private bathroom with shower, and a pleasant (shared) inner yard. Located ideally, literally minutes by foot from the museum strip on one side and the Albert Cuyp market on the other. Very convenient also for entering the Centrum down the middle, but considerably less crowded. The place itself is very quiet.
We met Marion only briefly (she has a friseur salon in the front shop, and was with a customer when we arrived); she was very friendly and helpful.
All in all, an excellent place if you're in town for a night or two, or plan to spend most of your time out and about." I can add that communication with Marion was great throughout and she was flexible with check-in time which was very much appreciated.
