I have the Europa too. It is a pretty roomy bag. My cell phone goes in the outermost tiny pocket, the middle pocket holds keys, pens, makeup, and the main compartment can hold a sweater or bottle of water. The side pockets are good for smaller gadgets or medicines. I find it hard to rummage on the go unless the bag is up higher on the torso (vs. hip)
The back zipper pocket would be ideal for your wallet, passport, important papers...
