For 1000 rs you might not get A/C Rooms, of course Good Decent Non A/c Rooms are available. Another hotel is Hotel Talera is also quite decent old style hotel and you get 3-4 bed rooms also for around 1000/-.
There are a couple of decent hotels in the Jungli Maharaj Road (Deccan Area) and you get A/c Rooms for around 1400. You can ask for Corporate discount showing your company visiting card and one does get discounts around 20%
