Pitampura/Rohini areas are good. Less power cuts and not water crisis. South Delhi has water /electricity problems.
South Delhi is best and Rohini is also a great area.if you afford then you can move for C.R.PArk in South.It is awesome area.
If you can pay,I suggest take an accommodation in Heritage city- Gurgaon.It has excellent security,dedicated parking,sparate visitors parking, parks, walk paths, centrally located ( at least 6 malls nearby, hospital, market, Schools, 24 hour power back with AC, excellent greenery, area well cleaned etc. The enitre Delhi is very crowded. you may get good accomodation, but moving on road is a pain. If the work place is Gurgaon, you can also try Dwarka society apartments as well.
I love to live in South Delhi. It is so pleasing. Less crowd and clean (nicely maintained) Areas like Green Park, Hauz Khas, Kalkaji are best to live
