I recommend you to the Bayi Hotel on Miao Wen Street. The hotel is the guest house of Heilongjiang Military Command. Needless to say, the security problem is certain, and it is located in the military compound. The surrounding area is quiet and the environment is good. In terms of price, the standard room should be less than 200, the room should be cleaned by a waiter every day, and the bedding should be strictly disinfected every day. If you care about quiet accommodation and don't want to spend too much money, that's perfect. Go and have a try. The statement is definitely not an advertisement. I lived in Harbin all the time when I went there:)
I forgot the address of 10. Miao Wen Street, nangang district. Go along this street and you will see it. It's diagonally opposite the Confucian Temple, and taxi drivers basically know it.
