The flat where I was living with a couple of students was one of two bungalows built on the flat roof of a Supermarket & Chippy near the corner of the road opposite shops & Post Office.
Never had any issues with my car that I parked down the side access to the rear - the Supermarket was burgled a couple of times when cigarettes & booze was stolen.
I've looked on Google Street View and the place has been demolished for flats. TBH it was a pretty run down area hence why the rent was so cheap. We used to go into Grimsby to drink at The Angel PH or the Tivoly Tavern.
