Pilots are taking leaves due to their hour limits. trainings are slowed because of this problem. As far as I know hour limitations are not knowingly exceeded.
Housing will cost more than the allowance that you'll be receiving. It's not clear yet what option is really better. Some new pilots are leaning towards arranging their own appartments, but when you're away 6 out of 7 days, it might not be worth the effort and money.
Also, there is a NG sim located outside Cenkareng as well. I should know since I've used it.
