What kind of housing are you looking for?
Parts are Oakland aren't horrible -- Rockridge, most areas in the hills and east of 580, etc.
Why not Alameda itself? There's only one bad part of Alameda -- former base housing southwest of the corner of Webster and Atlantic. Otherwise it's safe and very well patrolled (too well, in the case of the strict 25 mph speed limit). Good Mexican food at La Piñata/La Penca Azul.
Union City, Fremont, Dublin -- all very very suburban, if you're into that...
