We will not charge a fee for an initial request, but we reserve the right to charge an administrative fee for handling a request repeated with a year, or in case of otherwise manifestly unfounded or excessive request. Note that we will need to verify your identity to be able to act on any request. If we believe that we should not act on your request, we will write to inform you of the basis for our decision, and also of your options for legal remedy. Separately from these rights, if you believe that Danubius has mistreated you with regard to your personal data or your privacy, please contact us so that we can rectify the situation and improve our service to all guests. You can send a formal complaint to us by email or by post to the address given in section 1.12 “Contacting Danubius regarding GDPR” below. We will aim to respond without undue delay and in any case within in a month.
