Hi, nothing to worry about in DSA, good-quality school with experienced instructors and nice fleet. I have several friends from school who made there ATPL integrated and been happy. Have a look on F-Air as well, it depends from where you will travel onto training. I had my training in F-Air and except a lot of people in training in that times (so sometimes problem to book the aircraft) I was happy too. Don't hesitate to ask.
