Can you learn Spanish in a week?

Yes, you can learn how to speak Spanish in one week. It is possible but you will have to put a lot of effort and work into it. The human brain is familiar with the language you grew up learning. To learn a new language like Spanish then you will have to train your brain and teach yourself a new language. Programs like Rocket Languages or even Rosetta Stone help people train their brains on how to speak a new language very very fast and effectively. I would suggest Rocket Languages because it is almost the same thing as Rosetta Stone except it is much cheaper in price compared to Rosetta Stone. Check out the links below for details.
