Plugging my site, but only because it addresses some of your core complaints, and may be helpful. Dwellsy.com has the largest inventory of any rental property site out there, is aiming for zero fraud (and has quite a few features implemented to prevent against it,) parses descriptions to more accurately represent the actual amenities (it's decent, but not perfect) and doesn't clump units in apartment buildings into one ranged price listing, as we prefer to have the units represented as individual listings. Hopefully it'll help, but feel free to reach out directly if you run into issues.
