Hi there -regards from your other post! 🙂
I don’t know about Yerushalayim, there is one in Beitar called Yad Leah. I know that there is supposed to be a great one in Mattersdorf; unfortunately, I don’t know what it’s called but maybe another poster will help jog my memory.
If you can get a hold of a Madrich HaChareidi there is a whole gemach listing there in the orange pages.
Hatzlachah!
