At Wunderflats, the entire process runs directly via our platform. We will never ask you to submit a booking request via email, through an external booking service, or by any other means. If someone asks you to not conclude a rental agreement via Wunderflats, this contradicts our terms and conditions and is probably a fraudulent listing. In such a case, please contact our Customer Support Team:  phone: +49 30 120 86 22 0  email: service@wunderflats.com
