This place is great and Marga is terrific host. She is very helpful and full of energy. Though i stayed at her place for just a single night but had enough opportunity to not only meet and know Marga but to her family as well. The whole family is very welcoming and place is very unique compared to modern day establishments, you will be amazed to gaze at the sky on a starry night just outside your place from the garden. The location is pretty good to access the trams and city without any hassles, it's quiet and safe in there even if you walk midnight in the street. Margas' houseboat is awesome and it feels really good when you are in there.I recommend this place for staying and will try to stay there whenever i visit Amsterdam.
