Continental BusinessFirst allows access to Sala de las Americas in EZE but not to anyone else (per the CO website) and the lounge dragon turned away a couple of plats while I was sitting in the lounge. Surly does not even begin to describe her attitude either. I don't believe the invitation allows for any guests unless they are also travelling BF with you.

The smoking room of the lounge permeates the entire lounge with second hand smoke which can be quite noxious. There is a selection of decent free alcohol and self-serve soft drinks. There are some type of salty, crunchy unrecognizable bar snack in bowls available and mini-muffins in cellophane.

There are two computers with internet access and there is free wireless access available in the lounge (SSID: default).

The lounge is located at Gate 2 and CO flights are about a 5 minute walk away starting at gate 6. The lounge is listed in the Priority Pass directory so you could likely get in that way. The second hand smoke makes the entire experience extremely unpleasant however and unless you absolutely must have wireless access while you're waiting for your flight you're best served in the main terminal where smoking is not permitted.
