Thanks @DiscoTech! That helps! I'm making a list of those features that are important to me and trying to match it with CU.
Most important features: the program itself (very good) and the security issue(?);
Quite important features: climate (nice), living expenses (?), public transport (seems nice), political atmosphere(? I care about this quite a bit as an international student, minority and female);
Less important features: cafes and restaurants(?), museums and cultural activities(?)
I need to do more research on the features I marked "?" about CU. Welcome to comment on these if anybody knows anything! Thanks very much!
