Excellent experience! This apartment is spacious, clean, well-equipped and quiet. Beds were super comfortable with nice linens. Our family of four (including two teenagers) felt like we had everything that we needed. As others noted, the stairs are narrow but not problematic. The apartment is in a great area of the city with many wonderful cafes and attractions nearby. Joanna was an absolute pleasure to work with prior to and during our stay - very accessible, kind, and helpful. We followed the recommendations in her guidebook closely and found it much more useful than our Fodor's travel guide-especially with restaurant recommendations. We would definitely stay here again when returning to Amsterdam.
