This is a great place to stay in Amsterdam. It's a fairy tale setting on a canal. Close to everything. It was spotlessly clean and comfortable. it was well equipped with everything that we needed.
Maarten lives in the building and was gracious and quick to respond when we had difficulty navigating a couple of appliances.
You do need to keep in mind that you will be staying in a 300 year old building. The bathroom is really small, no more than 3.5 feet wide. But this was manageable for us and did not really detract from our stay.
I highly reccomend.
A tip: The Airbnb event "who is Amsterdam" is a fabulous walking tour.
