The apartment was very well designed and a pleasure to stay in. It was a few flights of stairs up but that's normal for Amsterdam, just the stair case inside the flat was quite steep and I wouldn't advise it for anyone who finds stairs a struggle at the best of times. We actually had to leave our large suitcase on the lower floor of the apartment as we didn't want to risk carrying it back down when it was full (this meant that we would have to carry up our clothes to get dressed in the bed room with our suitcase staying downstairs in the living space/kitchenette).
