You will not be able to access for free (unless you have a Priority Club card).

There are two lounges. One for $60 and one for $40.

The $60 one (SUMAQ) has showers and long chairs to sleep. Also provides non-limited alcohol drinks.

The $40 one (VIP Club) has a Wii and 3 massage chairs.

Both have internet access, (good) apetizers, fresh orange juice maker, big TVs, computers, etc.

Even the $40 lounge is faaaaar better than any AAdmiral's club and at pair or better than Flagship lounges.
