The official conference hotel is the Leonardo Hotel Berlin Mitte at Bertolt-Brecht-Platz 4, 10117 Berlin (NOT the Leonardo Hotel Berlin, which is in Charlottenburg and definitely not within walking distance of the venue). Thank you to an eagle-eyed delegate for spotting this. The link on the Information for Delegates page has been updated. If you have already made a booking, please make sure it is at the right hotel. As the conference rate was negotiated with the Mitte hotel, this will probably be fine, but just in case!
