I joined in London in September, and I have a quiet personality and are easy to get along with, and I hope my roommate is a girl. During the sharing period, don't bring people frequently, it's best not to smoke, have a good personality and love to be clean.
It's best to be within 30min of a commute from Tower Bridge
There are no big requirements for the room type, it can be a single room in 2B1B. Shared bathrooms require roommates to be girls.
