Flipping heck, mate, sounds grim. I take it you're a Mansfield lad? Portland street is infamous in Lincoln for having turned into a ghetto-ised dump. Avoid like the plague. Drugs, human trafficking and grooming are rife down there.
If you're in Lincoln again, ring round the Latinas, who often work in the LN1 or LN2 area, and are far more reliable than the Romanians. Not to mention safer.
