The room was big, very clean and we had everything we needed (bed linen, towels, shampoo, soap…). The beds are super comfortable. We had access to the kitchen and a terrace, to share with the guests of the other bedroom in the apartment.
It is ideally located, close to the train station and the center of Amsterdam (around 20/30 minutes walk and less than 10 minutes by bus). Nice and calm neighborhood with restaurants and shops nearby (I recommend Dignita for brunch!).
Kees was very flexible with the hours of arrival and departure and the self check-in/check-out makes things very easy.
I would definitely recommend this place and come back for my next visit to Amsterdam.
