I can highly recommend staying at Sanne‘s Apartment.
She is a great host, immediately replies to every request and gave us great tipps for restaurants in the area.
Furthermore she was so nice to grant us a late check out.
The apartment is very clean, exactly as on the pictures and briliantly located in the center of amsterdam.
All sights etc can reached by foot but if you are to lazy to walk there is public transport right around the corner.
Would definitely stay at Sanne‘s again.
