The rental strollers have a storage "pocket" (I believe it is mesh) on the back. There are no storage baskets underneath. You may be able to fit a small backback in it but probably not a big overstuffed one (like I'd bring )
Here's a link to a picture: http://allearsnet.com/tp/mk/mk_stro2.jpg
You can't really see the pocket or bag but its attached right to the back of the stroller. Hope that helps!
