As a student who changed states to study here at Parul, let me answer your question. The university is around 15-18 km away from the main city so forget about renting a PG. The daily commute will be very difficult for you if you decide to live in a rented flat or room in the city.
The best choice you can make is to stay in the hostel itself, which I have done. Here inside the campus, you’ll get all sorts of facilities, so you need not worry about going to the city.
