Co-working space/office

I need a co-working space or an office for a month. Requirements:

1. Odd working hours, will probably need access until at least 2 am.

2. Closed/walled space. Most of my work consists of online meetings so open desks don't work.

3. Just need a space for myself (and the occasional visitor, maybe)

4. Preferably near Gulberg or Johar Town.

Cost is not a major issue but would prefer something reasonable of course.
