Response from Nikos:
I do not think we were being particularly demanding. The problem with the mattress, which the hosts' review brought up, was really unexpected and that is why we could not have notified them in advance. My wife felt pain on her back after sleeping on the mattress the first night and that's why we asked if we could move its soft top part. First the hostess refused to let us move it but later that day she changed her mind about it. We were surprised to find that because of this we were considered demanding guests. As for the returned book issue, we sincerely regret that it arrived damaged.
