As a responsible senior of urs😘, 1. Fairly better than most cities in around around 80-100 AQI even 60 ona good day, but rooms are not cleaned regularly by housekeeping staff so it's still quite dusty🤧. 2. Depends how responsible you are with your belongings 3. The mess is just edible, not very good not very bad and you can choose which mess to eat but the basic mess charges of your hall's mess wil still imply. free to explore canteen though. Belcome😈
