Dynasty 8 is the online store that sells apartments in-game. You can buy this by bringing up your phone in-game, going to the internet browser and clicking on Money and Services. One of your group of four will need what's called a High-End apartment in GTA Online, which apparently doesn't come with the Criminal Enterprise Starter Pack. That hopefully won't be too much of a challenge if you know other people who have grabbed the game for free and have half-decent PCs. Crucially, you'll want three other friends to play the heists with (you can matchmake, but it's precarious, and playing all four heists with the same crew nets you a bonus payout).
To access heists, you either need to join another player's heist, or reach level 12 in-game and host your own. They still represent the best GTA experiences you can have in any game in the series. They're like the heists in GTA 5's main story, only they involve four players taking part in one mission simultaneously. GTA has five heists (including a tutorial heist), and if you're new to the game, you owe it to yourself to check them out.
