Too lazy to read the other posts. Caribbean Coast will get you that for your budget. There the E11A and E11S right down the building that stop in ICC, much more pleasant commute in my books.
I forgot what is the time range but during like 30 min in the morning you get like 7 of these buses running. The buses are super comfy and some of them even have USB plugs for your phone and wifi.
If you want to take the MTR you just get the coach downstairs that runs every 15 minutes.
Join the Caribbean Coast group on facebook you can find direct to landlord which makes you save on agent fees.
