Both the apartment and the host were perfect. Edith is very easy to reach, flexible, and extremely accommodating. She was able to help give us tips and suggestions and had a binder waiting for us with many resources for us to find exactly what we wanted to do in Amsterdam.
The location of the flat is great. Located towards the outer edge of the canal belt, you can easily walk to any of the main attractions in the city. We only took the city tram once, at the end of our stay, because it was raining and our bags were too heavy to drag to centraal station. Otherwise, we walked everywhere (Heineken experience, museumplein, red light district, dam square, Anne Frank house, etc.).
As Edith mentions in her description, the only true negative is that the apartment is on the top floor of a traditional Amsterdam house. This means that the staircase is quite narrow and steep, and could pose an issue for that reason. Otherwise, the apartment was adorably set up and decorated, and exactly what we wanted! Highly recommended.
