Wilco is an awesome host. The farm is really sweet and there are great amenities in the space: everything is brand new and eco. I had a great experience gathering eggs one morning: I actually saw the egg come out of the chicken!! It was amazing!!!
We were only in Amsterdam for a few days and wound up taking. Ubers in and out of the city which cost about $20 each way, so factor the cost of transportation in if you are mostly interested in the city.
But if you are looking for the sweet eco farm experience, this place is perfect!!
