I am so happy with S Line Taxis Grantham! I called four other taxi companies, all of whom rejected my booking because I was calling at the last minute. S Line Taxis really saved me today, and got to the train station on time. Plus Luke, the driver and owner of S Line was really friendly! He even gave me useful advice for finding a place to live at Grantham. 10/10 I would highly recommend this taxi company.
