We can only recommend staying with Hans. The location is right at the border of central Amsterdam. So you can avoid the tourist packed areas or dive right into, as you prefer. Hans is a nice and friendly host, taking care that you feel welcome. He offers a bike tour (takes about 90 minutes) explaining a few things about the peculiarities of Holland and getting you some sights the typical tourist probably doesn't get. Go for it!
Thanks Hans, we had a wonderful weekend.
