I have not had a baby here, but I have recently had a good experience with a doctor. There was a nurse who translated, fully, and she was wonderful. This was a private care facility that I only pay €10/visit on top of my health insurance to use but you can also join as a member and not pay anything. So, while I can't advise about childbirth or care, I can tell you that chances of you finding a good OBG is probably high... it just might take you a while to find one you like and that either speaks English or has a translator in the office.
