Two things to be aware of when renting a basement apartment: (1) personal safety, since it is more 'accessible' than higher-up units; and, (2) be sure there is a very good drain(s) and that it is kept free and clean of debris (leaves, etc.) because one good summer downpour and you won't believe how much water can get into your unit! This would include window well covers and a good drain at the bottom of open stairs. They also tend to be dark, which some prefer, and you don't have to carry heavy stuff very far, plus you'll save on your heating and cooling costs!
