The best areas for students in Newcastle upon Tyne share three qualities: they are close to at least one major university, they have direct public transport into the city centre, and they have enough shops, cafes, and supermarkets to be practical for daily life.
As a general rule, neighbourhoods with a high student population feel safer at night, offer part-time job opportunities in cafes and bars, and give you a built-in social scene. Ask your university's welfare office where most first-year international students live, this is usually the safest starting point for your Newcastle upon Tyne accommodation search.
