I lived in Kirkstall for 3 years and liked it as an area. good transport links to city centre (train station can be a bit of a hike from some parts, but busses are good), and easy access to the cliff, caley and points NW. Horsforth is nice too and has enough pubs, restaurants etc that you don't need to go into the city all the time. Same caveat regarding distance to station applies.
Monolith u told me u were moving to shef with mule. House was right "everybody lies"
any nice area of Leeds.
