All is good in CTN and it has a very class ship "Tanit" it's really amazing good food too.
Try to book directly from CTN website not from direct ferries,it the worst agency I have ever seen.
Lot of wasted time, waiting on the phone after that they told you send an email and as a reply to your email they request to call, and no possibility to amend / change your booking , I wanted only to change the car ,they request 112 euros in plus to do it however it has to be done by website but no way,and after that CTN told me that if I came to the port I could change it free
