I have a few friends from Karunya University. According to them, the hostel facilities are quite good. 

• In the first and second year, you will have to stay in 4-seater rooms with four random people. In the third or fourth year, you can change to single seater/4-seater/6-seater rooms. For single-seater rooms, you will have to pay an extra 5,000 each semester.
• Every room in the hostel is facilitated with a proper cot, tube lights, study table, clean bathrooms, housekeeping, and proper ventilation. You can also use a wall shelf for keeping your belongings. The rooms are spacious. However, the rooms are non-ac. 
• The hostels are safe. There is 24/7 security.
• The food and accommodation facilities are worth the money. The curfew time for students to enter the hostel is around 7 in the evening. 

Very few colleges in Tamil Nadu can match up to the standard of Karunya when it comes to hostel and accommodation. The hostel is very strict when it comes to discipline.
