When I use apple maps it shows my location as slightly next door with a wrong house number. I've reported the problem a few times. I don't really mind as the pin is close enough but using apps like day one which is a journal app that adds location to your entries. It would be nice if it said my house address rather than a different house on the street. Google maps also shows my location as slightly next door with a different house number to what apple maps shows. Both are wrong anyway. I've waved the phone in a figure of eight in both maps apps and the compass apps to try and re calibrate my iphone but I still get the same results. Iirc my iphone 4 displayed my correct location but its never quite been the same on the iphone 5 even using the good maps app.
