Here's the guide i used, it's a simple text guide that can be read quickly, it's gleaned from the IGN website but there site is full of adverts and can lag quite bad. It has been editted to remove any fluff too.

website that included too much description. However they have pictures for the harder to find ones if you're struggling and is an excellent compliment.
One note is if it says something like "to the right of the door you entered" it means, face the door and look right, not right as you enter.
