One of my friends graduated from NLU Delhi and also after checking the reviews online, I can share these details about the hostels, which might be useful for you. 

• There are no single occupancy hostel rooms provided in NLU Delhi for the LLB Hons. students. 
• Students studying in NLU Delhi definitely won’t be provided any single occupancy hostel rooms for the first year.
• But there are a few rooms available in the hostel that the management can allow you to use as a single occupancy hostel room, only if they are not occupied already.

Do keep in mind that a single occupancy hostel room here, only means a bed, a table and chair, a wardrobe, and electrical plug points and implements. No separate bathroom or anything of the sort is facilitated.
