University housing for international students

Hi, I'm applying for my exchange right now and Im really interested in Hong Kong. Im mostly interested in exploring the city and kind off messing around so I dont really care about the quality of education(not to say that I expect it to be bad at these universities). Because of that I either want to go to Polytechnic Hong Kong University or the city university of Hong Kong(The only 2 schools I can do an exchange to in the city center).

My main concern is housing, which I understand can be really expensive. Ive read that polytechnic guarantees housing for exchange students and that the city university of Hong Kong gives it to most international students, but that they dont give any guarantees. Im curious if anyone has any information about what the university dorms for international students are like, and how likely I would be to get university housing at the city university of Hong Kong.
Im also curious which university Hong Kongers would choose in my situation, and why?
Thanks for any advice!

(also if anyone from Hong Kong wants to do an exchange to Stockholm we could possibly arrange a swap of housing during the exchange period)
