I did that kit about 5 years ago, I believe. I used nottingham ale yeast, and fermented it at about 64 degrees, maybe a bit less. It was pretty darn good!
It was the first brew I ever made. The beer was great and I made it again. I went all-grain, so I haven't made it in awhile but I have been thinking of making it again.
Just did that one myself back at the end of July. I also used the provided yeast but I did do the "proper" Lager fermentation. It's beer, it'll turn out delicious. It'll probably actually have more flavor and character as an ale!
