Pim and Juan are amazing!! They are warm and welcoming. The room in their apartment is absolutely perfect for a single traveler with access to your own bathroom as well as a shower in your room. They were very easy to communicate with. And helped me carry my luggage up the stairs both when I arrived and when I left.
The location of their apartment is perfect. Right around the corner from Anne Frank's house. The entire city of Amsterdam is walkable from their apartment but it is well outside the craziness of the city center.
I would highly recommend staying with Pim and Juan!
