Have heard nothing but good things about the camp.
Fishing on Bisco is okay...not great.
I assume you're looking at this as a cheaper alternative to a fly in?
IMO Ramsey lake which feeds Bisco is a much better walleye lake.
There's one camp on Ramsey. Personally I've never stayed at it, only camped on the lake, but have heard good things:

In the same region and imo opinion a much better alternative to either is Wenebegon Lake west of Ramsey.
Five Mile lake lodge has a remote outpost on this generally inaccessable lake.
They take you in with atv's to a boat cache where you then motor to their outpost camp.
Very remote, very good walleye fishing.
