Visiting but have a question on where to stay

The wife and I will be visiting in early June and I'm needing a recommendation on where to stay, what part of town etc ... Thought about Fisherman's Wharf but 200$ a night is a little more than we wanted to spend. Were going to do mostly tourist stuff and thought we might stay somewhere cheaper and walk / public transit to where want to go. So question is where would reddit users want to stay in San Fran? Thanks for any info
