2. It is suggested that you can choose to rent houses along the subway of Line 5, such as Yuancun, Yun Ke Road and Chebeinan on Line 5, and there are many cheap houses around Xicun Station and West Station in the direction of the railway station. If you don't mind changing to the subway, you can also choose to rent a house around the station of Line 2.
3. I suggest you go directly to the rental website. SouFun and Fairness both rent houses according to the subway line. You can go up and have a look.
