Staying and Finding Accommodation in Bangalore

[arciere]

Hello there. I would appreciate if anyone could recommend me an accommodation suitable for a student in Bangalore. I am a PhD student working on my thesis about IT industry, and am planning to stay there from late February until May for my research. So far, the budget hotels and services apartments I have come across on the Internet are still too expensive for me. Thus I am wondering if anyone in this community could recommend me a place to stay or a more specific source where I can find information? I do not need an A/C room and I do not mind staying in women hostel or a rented room. It would help if the place locates near city centre as I need to go interview people.

This will be my first time going to India. Therefore, any other tips about living in Bangalore will be very much appreciated. Thanks.
