I get the vibes that ateres really dont encourage secular music etc. Apparently they confiscate cds of secular music, thats what i heard from a friend. so not sure if its too strict for you.
Ateres is in Ramot, so not so close to the central part of yerushalaim, but still in yerushalaim. Maybe a coupl of buses away from centre.
Its wuite a small sem, maybe 50 girls or so. but not sure how many there are this year. I also think its a fairly early curfew, i assume that means 10.30ish.
HOw about Midereshet tehilla? Its not a beis yaakov sem, but chareidi teachers. its on nevey campuss. the rav is rav Kehaneman, hes amazing. Thats quite hashkafic and non textual/academic, but also spiritually uplifting etc
