We booked this accommodation on behalf of my parents-in-law. Petra was very welcoming and accommodating, particularly considering that they arrived quite late due to a delayed flight. She was very helpful in setting up a spare mattress for our daughter just in case she had a sleepover here. Bear in mind that the space is up some serious Amsterdam stairs and is in its own right fairly small. There are also no real cooking facilities so this is really for guests planning to eat out. The area is great and the place is spotless so we would recommend!
