To the OP--

To the advice above, I would suggest joining one of the health/leisure clubs around town, such as the one at the InterCon and Diplomatic Club. They're largely populated by Westerners with few social restrictions, and they are pleasant places to work out and lounge (pools and beaches).

In terms of housing, living in a compound can provide an instant community network, but this can have downsides, too (think village life in England). If you go that route, just be sure to choose a large and reputable one. The West Bay is nice, too, but a little more isolating for someone on their own.
