The location could not be better right in the centre of Amsterdam.
The place is clean, have a large kitchen, two bedrooms and is perfect for a family. Our kids really loved the place!
I would have given five stars if it were not for the price. The place needs some paint, new and fresh linen, a few repairs (one of the sofas almost fell apart when we sat on it, and there is something going on with the sewer in the bathroom, which smelled really bad the whole stay). In its current condition, this is not a 450 - 500 euro per night accommodation, and there is definitely not anything luxury about it as one could be made by believing as the booking company is called "Luxury Hospitality."
If you don't mind overpaying a bit, then this place is great!
