How good is the IIM Ahmedabad hostel?

I assume you are asking about the culture of IIM Ahmedabad hostels, and not their aesthetics. 

The hostels at IIMA are excellent and filled with all the necessary facilities. They are referred to as dorms and not hostels, and 25-30 students live in each one of them. Dorm mates are very supportive towards each other. 

They wake each other up for classes, help each other in preparing for quizzes, and genuinely care for each other. It feels relaxing to return back to the dorms after tiring classroom hours. Chatting and gossiping with dorm mates is always fun. 

The hostel culture of IIMA is very warm, welcoming and friendly. The time spent over there is truly memorable.

One of my friends has shared his experience of hostels at IIM Ahmedabad. The hostels are called dorms and each dorm has a unique name. My friend was a resident of Dorm 9 which was an old campus dorm. You will find a unique culture, rules, a representative and even different birthday norms.

• Every dorm has a total of 30-40 rooms with single bed for every student. 
• There are rooms with dual occupancy but only for married couples. 
• Most PGP students stay in single rooms.
• Each dorm is divided into 3-4 floors with basements in a few. Students cannot access terrace in most of the cases.
• The facilities offered with each dorm includes washrooms, kitchen, automatic washing machine, refrigerator, microwave and many more.
• The institute has assigned a care taker for each dorm and a security guard at all times.
• Other amenities include Bed, Mattress, Fan, Mirror, Study table, study light, whiteboard, curtains, shoe rack, cupboard, chair, and many more.
• You will find ACs only in a few dorms but the institute is planning to install ACs in all rooms. 
• You can purchase a cooler or even get it on rent from the vendor inside the campus only.
• Balconies are attached with all of the rooms except for basement ones. It gives a scenic view of the surroundings.

The rooms are allotted on a random basis but you can change them after 1st year or in case of any medical conditions. If looked from an overall view, the hostels are pretty comfortable, welcoming and secure. 

The only drawback is that you will find in the hostels are mosquitoes and the heat. However, the administration is doing their best to solve such issues.
