Louth is about 26 miles East of Lincoln, 15 miles South of Grimsby, and 32 miles North of Boston. Set satnavs for LN119YN. From Lincoln and West take the A157, from North and South the A16. For directions from where you are scroll to bottom and fill in your starting location, but type "UK" after the text to avoid being directed from the USA!
NB the location of the cottage is actually to the West of the marker on the map and on the South side of Westgate.
