we're neighbors! i'm on 52nd and 21st.
anyway i was the guest that posted, it wouldn't let me log in at the time. yeah i don't think it should deter anyone from coming here either. but i think in the end, i wouldn't really strongly reccomend living in the university district. i've been here for 4 years, and i just think it is appalling for all sorts of reasons. granted, it is convenient, but there are better places to be living in seattle.
neighborhoods i'd reccomend for those without a car (i.e. like me): greenlake, wallingford, ravenna, fremont, ballard, university village, capitol hill
without a car: greenwood (you can manage without a car too, just some parts of greenwood it can be annoying), queen anne, northgate (maybe)
UW has some grad housing too, i think its radford court for grad students and there's something else i've seen behind the university village but don't recall its name. i think that nordheim court is generally occupied by undergrads, but i think they have studios or one bedrooms there as well. actually there are more that i can't think of, but i'm sure the housing site has all the info.
