The place is a beautiful space but unfortunately lacks "love" to be a great experience. The furnishing varies between high end and not so much, and the amenities are minimal, making the place less practical than it should be for an Airbnb. For the rate the hosts are charging, they should think of including a few more amenities to make guests feel more at home. The in-built cupboards in the kitchen have a few additional amentities but it isn't all that clear that they are for guests' use.
The hosts manage the property through a woman called Madeleine who is friendly and helpful. She helped resolve the small issue we had promptly.
Final point, as is typical in Amsterdam, the staircase is very steep and the place under Gianni's has two floors, so it is quite a climb, at times a bit uncomfortable with an infant.
