Be aware of scammers
It has come to our attention that certain organisations and companies, which are in no way affiliated with ESSO, are falsely claiming to act on our behalf.
Please be advised that www.esso44.org is the only official platform for registration and congress-related information. We strongly recommend that you avoid using any other websites for congress registration.
For hotel booking we advice to book your room using our hotel booking link, the official website of the hotel or a verified travel agent.
The only other companies involved in the organisation of the event besides ESSO are C-IN (@c-in.eu) and Gothia Towers (@gothiatowers.com).
If you have any doubts or questions, do not hesitate to contact us directly.
