Hi, think I can help here.
Its half of 24k which is the starting salary for a low hour'd cadet until line training completed, (so basically yes, 12k pa Euro)
They put you up in a hotel during the training at their expense, and throw in breakfast too! When you go home/have time off you can just leave all your stuff in the hotel room.
I haven't the pay scales to hand but what I was shown yes the pay does rise fairly quickly especially upon unfreezing of ATPL.
Sector pay is a great feature of the job, tax free and adds between 2-3k Euro on top of salary.
During my training they put me on flights home for the weekend when I asked on their network for free.
Absolutely no complaints, they treat you us very well. Any more Q's feel free to PM me.
