Roel was incredibly welcoming, and the windmill itself was very beautiful- a really unique experience when staying in Amsterdam. The only downside we had was that the windmill was much further from the city centre than we were expecting- the listing says 15 minutes, but in reality it was closer to 40 mins, especially as the buses at the weekend are not so frequent. Not a massive issue, but worth being aware of if you plan on going to the City centre a lot.
Otherwise an awesome place to stay, and thank you for having us!
