Postgrad accommodation options

Hey everyone, can someone tell me if these (https://www.accom.ed.ac.uk/our-accommodation/?student=Postgraduate&catering=&room=) are the only accommodation choices for postgrads?

I'm trying to apply for a place but the EUCLID portal isn't working for me, so the helpdesk asked me to email my top 5 preferences. So, Just want to make sure this list is up-to-date.

Well, these options seem pretty pricey. I guess I should start looking for outside options also, as well as trying to get a spot in the uni's accommodation. Whats your thought?
