First of all, welcome to study and live in Sichuan. The school you mentioned is better in Sichuan and the conditions are better. Accommodation depends on yourself, and you should choose between 4 people and 6 people. The cost is 300+ a month, but it is usually 400-500. I don't know what luxury is. As for how far it is from the city, it depends on which campus. If it's the headquarters, it's closer.
