Other Assistance Services:
Some larger lecture halls have induction loops.
Residence Info:
I did not receive information from the housing PSOAS, but they would be the place to contact for further inquiries.

There are many different housing options provided by PSOAS, I assume that at least some of them are accessible.

I believe most residence halls have saunas and laundry rooms which are accessible. Some residence halls also have gyms.

I believe the sauna is accessible. Also I believe all the cafes and restaurants are accessible.
