I will choose to stay in a 3b2b at the South Tower when I go to Manchester in September.
Those who have previously done their research should know about this location. It takes about a 10-minute walk to reach both the South and North campuses of Manchester University.
Therefore, there are quite a few Chinese international students living in this area, and on top of that, it is convenient for dining and shopping.
Another point is that it is sufficiently safe.
π‘This is a 3b2b layout, which can accommodate at least three people, and it includes bills, water, and electricity, so you don't have to worry about those.
As for the safety of living in other places, I really wouldn't know. After all, it's my first time coming here...
