Retiring rooms at SBC are outsourced to some private company (can't recall the name) and are maintained average... (Over all citing exterior, room interiors of both AC and Non AC).
1. After you enter the station (dont enter the PF, PF 1 side) from taxi drop/pickup point, move right, beside milk parlor you will see stairs. Take that and go to the reception situated on 1st floor. (Do take a look at the wall paintings on the walls of station interior from here) Fill a form and mention transaction id, amount paid, phone no. and after entering details, manager will give you the keys.

more... A. Pic 1&3 are of Suit C which cost around 1000 (actual 998 after 5% discount on online booking) for 24 hrs. The room was well maintained. The beddings were clean with not the usual Railway blankets (2 fluffy soft blankets are provided). The toilets were OK with hot water tap which worked. The TV displayed all the major channels. So worth the price. From the corridor of Suit rooms and deluxe rooms, one gets a view of SBC station PFs.
B. Pic 2 &4 are of non AC room which cost 600 (570 on online booking). This room was somewhat not good. No TV (despite mentioned while booking), loose plastered walls which had fallen from here & there, some creaky furnitures. Toilets were same as of AC room/suit and were clean. The price was not at par for non ac room.
MY TAKE : If you wanna go for Suits, book it. Non Ac rooms are not worth the price. In that price one can get a better room in nearby hotels.
