What is a good website where I can search for apartments?! Something where I can filter with lots of details would be nice.
http://www.rentals.com/ Once you enter the city it will bring you to a page that has filters on the left hand side.
MLS they tend to have alot of different listing, including commercial spaces!
I'd suggest homefinder.com. Here's a link, http://www.homefinder.com/rentals/ .
