My brother was an M.Tech student at JNTUH a few years back. He lived in the Krishna hostel during those days. According to him, you should not expect much in terms of facilities. The hostel is comfortable but during the rains my brothers’ room got filled with rain water and he had a tough time protecting his belongings.
The greenery of the campus is soothing and the playgrounds are nice. The mess food is limited in quantity and is pretty average in taste. The hostel administration is slow. Some of my brother’s friends used to sleep in the library and TeQip when their rooms got affected with mosquitoes. You will find the TeQip and library much better places to study rather than the hostel.
My brother did not have a pleasant experience at the JNTUH Kukatpally boys hostel as an M.Tech student.
