Hi Adele,
Thanks for getting in touch. I'd suggest contacting the organisation you’ll be working for, as they may be able to offer advice on local accommodation options or point you towards useful resources and contacts.
You could also look into local community or accommodation groups on Facebook, where short-term rentals and rooms may sometimes be advertised. You may also find useful information through
Citizens Advice.
I hope you find somewhere suitable and have a wonderful time in Belfast.
Regards,
Eoin
