By law it's a secret court to begin with. Whether or not there's a sign on the door, it's still a secret court. Would a secret court that advertised its location be more palatable to you somehow? Because a sign on the door adds zero significance to the substance of the FISA court's existence or powers.
And, given that it is a secret court, well it wouldn't be very secret if everyone knew where the courtroom was, would it?

For me, yes, what is secret about a secret court matters.
Classified proceedings? I think there could be room for that, within reason and with some kind of oversight.
A court that makes a secret of its existence? No way. That makes oversight more difficult -- one of the few who oversees it can't make a democratic issue of how it operates.
A court that makes its rules and workings secret? Nope.
A court that makes its location secret? Not sure if that's particularly bad if everything else is on the level, but I also don't know if it's necessary, and keeping the location secret seems like a step towards forgetting it's there and what it's doing. So I'm less comfortable with that.
