I am assigned with project that can last 6-8 months and planning to rent an apartment in Shenzhen.

You can consider Ju Jin Yuan Serviced Apartment on 33F, Hong Kong Island Ginza Mall, No. 3002, Jiefang Road. The hotel is adjacent to Exit G, Longgang Station. Metro Longgang Line or Luobao line. You can easily spot it. It provides clean environment and nice service, and it charges reasonably. You can have a try!

For vegetarian food, you can go to Yun Lai Ju Vegetarian Restaurant on 4F, Dongmending Fashion Shopping Plaza, Yongxin Street. It is adjacent to Exit A, Laojie Metro Station. :)
