Don't worry. You're not the only one. Natives are often lost. Couple of times already I've been asked where the given address is by Japanese person and I am definitely not of Asian descent :) On the contrary, in 2008, before the mobile Internet I was looking for an address and couple of natives couldn't find it despite the fact I got address and a picture printed at hand. Turned out we've standing next to the building and all I had to do is to turn back to find it. Today I just follow uncle Google advice.
