Unfortunately the dojo can not house foreign guests for overnight stays, since the hall is rented and not owned. There are however very good and affordable accomodations available nearby the dojo.
Stay Okay Haarlem offers reasonably priced accommodation and is only a few minutes walk from the dojo.
An alternative option is the business-hotel Bastion Haarlem, where we usually house our teachers from abroad on their stays in Haarlem
