We had a great stay in Jos apartment and enjoyed our stay in The Hague.
The house is very well equipped and we did not miss anything - we were even offered to use the two cargo bikes the family owns so it was easy to get around the city and really feel like a Dutch family.
We stayed in the house with four adults and two kids and had plenty of space given the number of rooms and beds available (one of the queen beds was located in an open space on the top floor though).
Sammy the cat was nice and relaxed, even with two young kids around.
Communication with Jos before and during our stay was easy.
We can definitely recommend his place!
