Need suggestions on where to look for a flat.

Hi, I will be moving to Gurugram in January; my office is in Phase 2 Cyber City, near the metro station. Where should I look for a flat? My budget is ₹25,000-₹30,000 for a fully furnished 1BHK. Should I look for a place within walking distance of my office, which I understand will be expensive? Or should I look for a place near a metro station and get a better deal?
