Admin, town and city boundaries are in many ways hit and miss with nominatim, however that is generally through a lack of osm data. Or better said just having points, where it is difficult to estimate the size. For example according to Nominatim Surrey covers most of London http://nominatim.openstreetmap.org/details.php?place_id=559111 (Which it doesn't really). By using Polygons for the boundaries in the osm data instead of simple points, it will be more likely to give a more accurate result. Another problem is that place names can be fuzzy, as one person will say place x will cover a certain area, however another person will say it covers a different area, yet officially that's wrong.
