So, I suggest you settle down in your place after you arrive in Shanghai.
There are housing agencies in all districts of Shanghai, and they are all practical and reliable! Shanghainese would rather pay an intermediary fee when renting a house, and they are particularly willing to find an intermediary company to rent a house. The form of rent is basically three to one, that is, three months a month. You can find a shared house with two bedrooms and one living room within one week through them, and one of them will be rented to you, and the poor condition within 15 square meters is about 500 yuan/month. In that case, your first rent will be 2000 yuan, plus the agency fee 150.
Another way is to log on to the "Shanghai hotline" and use the information of renting and sharing to find a house.
Just a few days after I arrived in Shanghai, I couldn't find a house at the moment, so I went to the vicinity of the Shanghai 80 thousand stadium. There is a special job fair on Saturday and Sunday, and there are advertisements for college students' job-seeking apartments. You can look at it first, but you can stay if it's not good. Pay attention to how many people live in it.
The house in caohejing is cheaper. You can find a house in Donglan Road, Cao Bao Road, and there will be rooms or single rooms for rent!
