Renting an apartment is a special kind of nightmare.
While I want to believe there are good, decent, human landlords out there--I have yet to meet a single one. Landlords know they can take advantage of tenants because living situations take up a massive majority of everyone's income. Fixing broken appliances or even potentially dangerous apartment problems costs a lot of money, and most landlords would rather just let is slide until you report them than do the extra work of creating a comfortable home.
I've had landlords enter apartments unannounced, massive leaks, illegal rent hikes, and appliances so broken they're essentially just toy props. City living is already hard enough, and renting makes it a whole lot harder. So, when #VentYourRent started trending on Twitter, enraged renters everywhere were ready to share their horror stories from apartment living.
