I can't say enough good things about staying with these two. They are warm, generous, and insightful.
The room has a great view and some lovely details. Sound transfers through the house very easily though so bring earplugs!
Other things to note:
-Gerard gives excellent boat tours. I did a tour with him and with an innercity guide. I recommend taking advantage of his service :)
-Joke is an amazing cook. Be nice and you might get lucky enough to try her food.
-The STRAAT is incredible and only a 15 minute walk from the house. If you like contemporary art even a little bit, DO NOT MISS OUT.
