I've been in the market for an apartment in Mountain View (and recently leased one), and found that it is almost impossible to find an apartment building (run by management) that doesn't get horrible reviews on ApartmentRatings.com. Which is unfortunate because unless you really dive in, the tool becomes completely useless - - it can't be that every apartment is really that awful, and yet the only people who post reviews are those who are pissed and those who are shills (probably the management company themselves). I found internet reviews of apartment buildings completely useless in this regard.
