Hello!
I can't help you with that as I live with my husband in a flat. I would recommend student halls, private accommodation or look at share rooms websites. There is a lot of house sharing in London.
I would like to ask about the entry requirements about the dietetics PgD/MSc at King's College. The website and the admissions office are both very vague. I would assume you have finished with a 1st class Honours.
Did you have any dietetics internships during your undergraduate? What about the interview?
Kind regards,
Agata
