Definitely recommend Karina and Hans's house if looking for somewhere to stay with a group or a family, that isn't too central but is still within walking distance of most major destinations in Amsterdam. Lots of space in the garden, kitchen and living area to relax and unwind - the garden is especially nice when the sun is out.
Located in a nice area which isn't too busy or noisy but has some nice bars and restaurants nearby.
Unfortunately didn't get to meet Karina and Hans however the communication was excellent from booking all the way up to checking out and they were kind enough to leave some beers and snacks for us on arrival - great hosts.
