Of course, many (actually, most) of my apartments are rented as the result of word of mouth, so it's not been a big issue (and whenever I advertise on Kijiji or craigslist I get a hundred or more requests for showings). Nonetheless, it's frustrating.
It's also offensive to me that aside from claiming that my building have bedbugs, the poster states that "The landlord likes to act like some sort of Jesus figure/Socialist landlord when you meet him. The problem is when you complain he screams and hollers and won't spend a penny to deal with the problems!"
In the case of Dalton he wrote that "I rented there after being assured it was safe and it looked clean. Only after I signed the lease and paid first and last did I find out the place is full of bedbugs! This landlord has a habit of this. He acts nice to get you to sign the lease and pay, then you getting bitten when you sleep and he won't pay to fix the problem!
Perhaps I'm being a bit too sensitive...
