I chose it myself, but if you come late, there will be no 1500. There are 6 people in 800, 4 people in 1200 and 2 people in 1500; Among them, 1200 has a separate toilet, and other prices have toilets on the first floor. Of course, the network cable is self-provided, and the conditions are very general. I heard that the accommodation for graduate students should be improved. I don't know if it is true. Since you have chosen, don't regret it. I wish you success in your studies!
