Roel was a great host and let us have complete run of the windmill and property. Check-in and out was easy and completely flexible. When Roel got home in the evening, he showed us the milling mechanism - including the original gear wheels from the 1600s which he still uses to pump water from the adjacent canal. So cool! He also unleashed the mill's wings so we got to see the whole thing in action. Without a doubt, if we return to Amsterdam in the future, we will seek to stay with Roel again.
