Maple house nice place to stay. Just situated outside the busy, noisy and touristic centre, I think you can enjoy the 'real' Amsterdam. Quiet at night, but nice restaurants and bars are just around the corner. Metrostation and trams nearby, but a walk to the city centre is also very doable. This place maybe a bit more expensive to stay (with two people), but if you are looking for much living space and comfort it's well worth it.
Beds are fine, everything you could possibly need is there. Checkin through the key box is also very convenient.
Tip: when travelling by car, you can park it for a longer period (week) at the RAI for 60-70 euro (book a ticket though Mobipark).
