New offer doesn't look at all exciting for your degrees and experience. Try to negotiate if possible.
Bachelor accommodation may mean one room in a multi-bedroom flat to shared room with someone. You will need to clarify that with company. Also with 7000Qr basic salary, it would not be possible for you to bring family in future.
Overall, I don't think new offer is worth a change. Qatar is boring place than Dubai. Think about that as well.
