Ramona and Daan were amazing and very generous hosts. Even though we didn't get to meet them on this trip, they were very responsive to our questions and made sure a friend was at the house when we arrived to hand us the keys and give us a tour of the house.
The house is much larger than it appears in the photos and the layout worked for us as a family of 3. They had plenty of toys to keep our 5 year old entertained. The neighborhood is outside Amsterdam central on the north side of the IJ. We biked to the free ferry within 10 mins. The neighborhood is also great for a family traveling with kids, as there are several playgrounds within walking distance.
I'd recommend staying at Ramona and Daan's place and would definitely stay there again.
