My brother had the pleasure of staying at hostels 9, 16, and now 13 in chronological order. However, he claimed not one hostel had the complete facilities one expects in a hostel. I have described each hostel in a few pointers 

Hostel 9

• Extremely small room difficult for even 2 people to share
• The best food in the entire institute is served in this hostel
• It has many facilities like a pool, a small footer field, basketball court, table tennis and makes your leisure time great 

Hostel 16

• This hostel has some of the best rooms in the entire institute. The rooms are double occupancy but can easily be shared by more people.
• If you are lucky enough to be allotted the 6th floor or above, you can get a spectacular view of Hiranandani.
• The food is not very good

Hostel 13

• The room is usually for PG or DD students
• The rooms are single occupancy and are decked with decent facilities 
• The food in the Mess is neither too good nor too bad.
• The hostel has a wide range of extracurricular facilities. There is a TV room that can accommodate around 70–80 people. 
• This hostel is most coveted because of the spectacular view of the Powai lake and the Hiranandani it offers.
