The day we arrived, there was a severe wind, rain storm throughout all of Netherlands. Martin needed to cancel our reservation at the last minute because his building sustained wind and rain damage which knocked out electrical service. He communicated quickly and gave us a full refund immediately. We were able to save our holiday plans because mood to a hotel.
We later observed that many large trees were down in Amsterdam and many roofs sustained damage. It was an act of nature, not a fault of Martins, that we were unable to use his apartment.
