Although we were right on time (16.30) for a guided visit of the castle, the two ladies at the reception were very busy on the telephone, without taking notice of us. Because we were tired of waiting for attention, we asked one of these ladies when the guided tour started. She said that guided tours are given on other moments (which was not true) and went away. The other lady stayed on the telephone for more than 15 minutes. Disappointed we left the reception after waiting. We did not visit the castle.
Final conclusion: a very unfriendly and unprofessional welcome!!
