Finally getting around to making a belated report from my trip in November. Nike's contact was brilliant, stayed in a apartment about 5-10 mins from the plaza. This thread proved it's worth in gold, all the tips etc came in useful.
It's also worth noting that tinder is a strong tool to utilise as well. I got quite a few freebies this way. If you match meet for coffee and invite them back. These girls didn't even accept taxi money lol. I didn't really bother with the nightclub scene.
In summary, follow the advice in here and keep your wits about you, and you can't go far wrong.
