The ultimate test for a host is in adversity, and Willem did amazingly well. When we arrived, the building just had a new boiler installed, which the construction workers did not connect properly. Thus, at 8pm, I discovered that there was no heating. I messaged Willem and he replied right away and brought a space heater for the night. He also inquired with building management regarding the boiler, and everything was fixed the next morning.
Otherwise, the location is as good as it gets for tourist purposes!
