Yes, here you you see it's guess at where the boundary of Mastholte is
(using the 'details' link when searching for 'Mastholte, Germany':

http://katie.openstreetmap.org/~twain/details.php?place_id=866452

It's very hard to guess these things correctly - for instance this
would be very large for a village in the uk - more a town so making it
larger would probably break other places.

BTW - 'Alt Hammoor 36, Germany' does work.
