Our family of 5, with 1 extra stayed at Jo and MP's apartment in December 2012. Jo was extremely helpful prior to our booking, and provided us with plenty of information on what to see in Amsterdam once we arrived. The apartment is very close to Amsterdam Centraal Station, and is situated in a lovely part of the town, with everything you would need nearby. As with any Amsterdam apartment, the stairs are very steep, but this did not detract from our enjoyment of the apartment. I would thoroughly recommend this apartment.
