Semi Furnished is only the white goods (AC, Fridge, oven, dishwasher and washing machine) and you have to get everything else.
With fully furnished, each tower is different; some of them will be fully kitted out, where you just bring your clothes, while others have most of the furniture but will require the bed linens and kitchen crockery and few bits and pieces.

And as someone mentioned, you'll find cheaper deals here than what's advertised online, as there is a low demand on accommodation compared to availabilities.

Generally, you can turn around a tenancy agreement here within a week, so won't take long once you find a place that suits.
