the hotel is conveniently located next to a transit center, and priced much better than hotels in the city center with smaller rooms. it would have been perfect for staying in amsterdam if some staff could be more polite to their guests. they didn't have to be rude to guests not familiar with their facilities, e.g., when guests thought the slow revolving door stopped working and tried pushing it gently, there was absolutely no need to yell at them, at least to the ones didn't appear to be children or idiots. just tell them the door is automatic, they will slow down.
