Have to concur with the others. American is the best. Have known a few nurses in my time here and all were relieved when the American opened up. The Wellcare is the other decent one but believe their package is not as good as the American. Make sure they give you a housing allowanc but I suspect they will privde you with a shared appartment. Ticket home each year is essential. Transport allowance. This place isn't getting cheaper so try and negotiate as hard as possible with them.
At least you're close to The Lodge from there for a post shift beer or two. Then there is, dare I say it the Cyclone but best avoid that one....
