One day before arrival owner called that a mistake was made (he made it appear that it was due to the booking site, but in fact it was he himself who made the mistake) and there was no room for us. This despite a confirmed reservation. He was not willing to find alternative accommodation. He said that was not possible as every hotel in Valkenburg was full. This turned out to be a lie. Never had an hotel calling me one day before with a message that there was no room for me in my 40 years of travelling. I would advise not to book there if you want to be sure that you have a room. Having a confirmed reservation does not mean anything apparently with this hotel. Very unhelpful, unprofessional staff who dont take responsibility for mistakes they made. There message was: sorry, mistake, no room and sort it out yourself.
