As for the apartment Gotti used to conduct meetings, he probably assumed that the F.B.I would never bug a civilian's home. Well, we all know that ain't the case.
Well I can give him a pass there because with the situation he thought he was truly ok as nobody seemed to know where he went when he left the Ravenite and would disappear. I think it was sheer luck they noticed the old lady leaving at a certain time, etc. and they hit the jackpot.
