I have done something similar, more hours but in less time. . You are already noticing a problem, that's good. Taking your holidays shouldn't be a problem. Talk to the partner company and mention the European holidays. There are different ways to do this, the honest one is telling upfront. If your partner is not understanding, mention that you are going to work only from a co-working space, because of trouble working from home. The co-working space isn't open on European holidays. If all else fails, change endeavours. You are in Europe, not China. Plenty of IT-jobs here who respect work/family. Ps. The elephant in the room is not finding work, it's for your partner company to find trustworthy/skillful contractors.
