Not sure about bidet. Went for their maternity tour yesterday and it was really helpful. Can consider going if you got the time to. As for wards, I think the risk is only not being able to be admitted to double bed as the service staff said that they only have 2 bed * 4 rooms so it’s always occupied. Single has 40 plus rooms so it is hardly fully occupied.
Stayed in single room and there was no bidet in the toilet
