Use your first full weekend in China as a time to apartment hunt. EF will give a list of bilingual agents on the first day. You can start reaching out to these agents throughout the week, and use the weekend to actually view the apartments. You have full control of where you live and who you live with. So don't rush and don't stress, as two weeks is more than enough time to look for a Chinese apartment. When you talk to your agent, be sure to give a list of requirements.
For example, recruiter Harris' three requirements were:
1. Being close to the metro and within walking distance.
2. Having lots of natural light as waking up with sun shining in makes for a homier experience.
3. Stay in the price range!
Recruiter Joanne lived in Beijing had 2 roommates and her requirements were:
1. Have an apartment close to the metro.
2. Live somewhere with amenities nearby; like a grocery store, post office, and bank.
3. Live in a traditional lane house (called a hutong).
