We had a great time at Sean's place. It is not centric, but it is a quiet and family friendly neighborhood. It is close to public transportation (200 mts) and it takes around 20 minutes to get to Amsterdam Central.
Sean was always very friendly, communicative and helpful. I would recommend his place for families with young children or a couple. Just double check with him anything you really need from the list of amenities. He will make his best to help you. In our case, he provided a crib and it was great to have.
Just a final note. Unlike other airbnbs you will need to bring your own essentials (shampoo, conditioner, soap...) Nothing you can't live with, it's just for you to plan ahead.
