I stayed in this apartment for a long weekend with my mother and sister. We slept comfortably and the apartment was exceptionally clean with a great bathroom.
For us the best part was the location. The apartment is right next to the museum area in Amsterdam and we walked into the city center to do the rest of our sightseeing. There are plenty of cafés and restaurants in the area for breakfast / lunch / dinner.
All in all this was a great stay for us, I would highly recommend renting this apartment!
