The easiest way to contact us is to use the chat-popup at the bottom of every page. This is answered personally by us, not a robot.
(Robots are expensive, and not yet good at dancing, so we don’t let them answer.)
If you write in Deutsch, Roberto will answer.
If you write in English or Spanish, Vio will answer.
Our favorite messaging system is Telegram.
(It works like Whatsap but not owned by facebook, and allows editing and deletion of messages.)
