i would like to work in a hostle/guesthouse. How would I be able to get that visa?

Emilio, I am afraid that it's very difficult for you to make it happen. You need to apply for a Z type. In order to get it, you need to acquire the work permit first. You need to ask your employer to assist you to apply for the work permit. If the hostel isn't qualified for recruiting foreigners, then you can't get the work permit. Therefore, you won't acquire the Z type.
