My mother in law and her hubby moved to grantham couple of years ago, we visit quite often and find it quite nice.... oooo and if ur near the castle they have a fireworks competition every year (august i think) which is an awesome evening... weve been for the last 2 years....
not great info to settle you but from what weve seen it seems nice, where r u near? they arent far from the asda?!
