I am currently in Yishrei Lev, coming here was one of my best decisions ever. The yeshiva joins the right proportions between Rebbeim and Talmidim, and the Bochurim here are none other than great. Yishrei Lev is diverse in the student body between different High Schools/Mesivtas throughout America and Canada. The Location of Telzstone I love the most for it is only a 20 minute bus ride away from Yerushalayim, but still far enough not to get distracted from the city life there.
But you should really check out their website.
