PGs are good over there, AFAIK. But see if it fits your budget. 10k for single or two shared room is a bit on the expensive side.
Some companies offer like a 1 week accomodation for people who are shifting to BLR. So, check if you company offers that. If yes, take it up. Once you join the company, you can talk with someone you meet on day 1 or day 2 about accomodation or maybe with your reporting manager if he's super chill about it. You might get far better suggestions as they have been through this phase as well and knows the area better.
That's how I got two really good deals and closed on one.
