Which is the best hostel in IIT Bombay and why?

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.
