We stayed at Eriks house with our two small kids for a few days and had a wonderful stay. Erik was very helpful and made an extra effort to provide beds for the kids along with ample information about the house and Amsterdam. The house was very nice and we didn't miss anything. Our kids had fun playing both inside and outside and it felt safe. The only thing that we were worried about was the steep stairs to the bedrooms upstairs. We relied on the public buses for transportation and that worked out well. Beware that some lines go beyond the GVB network and we had to fold up our stroller a few times because the buses were crowded.
All told a heartily recommended place, particularly for families with kids!
