Surely it depends on the circumstances, which the OP has given little detail about?
If the OP is commuting to a city for a high paid job, it's fine, but it's not, it's NMW.
If the OP lived in the middle of nowhere and there are no jobs locally, she should probably take it on a 'needs must' basis, but seeing as she has the luxury of 5 trains an hour, a five minute walk away, she's probably not in those circumstances either.
If she really did live in the middle of nowhere, there would be one bus a day in each direction if she was lucky and it may or may not match up with her work hours. And if that bus missed for any reason, she wouldn't be able to get to work, or would be stuck at work and face an extremely expensive taxi journey to get home.
If the OP was in the situation where someone expected a person who lives in Leeds to travel 2 hours a day to work in a shop/warehouse/care home in Manchester, you'd be mad to take it, because you'd just get the same sort of job on your doorstep.
