Hope your expectations are not so high. So less offered for that amount of money you pay. We´ve paid 400€ a night for 6 people, i know Amsterdam is quite expensive but at least it could be ok if we have found quality and cleanliness. Old, small and different towels.
Make sure you are ready for noise between 10pm and 4am on weekends.
Stairs to get to apartment are very narrow so difficult and dangerous with big luggage.
