Great location!! Loved the spot. It was close to Centraal train station, public transportation, and much more to make your stay in Amsterdam fun and easy. As others mentioned, the stairs are narrow. And, the front bedroom faces the main road that is lively. People walk around late and are loud. You may need ear plugs if this will wake you up.
The bakery around the corner—Niemeijer—makes great bread and the pastries are good too. Also, Sango coffee, which is nearly next door to the place is great too. Local roastery and friendly staff.
Best of all, Kobe and Eva are great—responsive, understanding, helpful. I definitely recommend their place. Enjoy Amsterdam!!
