Are you working through an agency? If you're paid offshore you'll not have to pay Trinidad taxes; otherwise, look out.
Our apartments never materialized, especially since the company wanted double occupancy. Looks like they've gotten used to the idea. Trincity is close to the airport.
We flew about 60 hours per month, but this took 18 - 20 days, IIRC. There was a lot of back side of the clock stuff. (YYZ-POS, for example).
You'll get a monthly roster a few days in advance, but it gets butchered as the month rolls along. There wasn't much reserve, and you'l probably get assigned a trip the day before anyway. They were quite short of pilots last year.
The plan last year was for CAL to fly the 767's. That was last year, though.
They were wet leasing some North American 757's for other things, though, so who knows?
