Not sure how to do link but she advertises on gum tree
Under north London section
I suggest you work it out if you want any help. IMO it's taking the piss if you expect other people to look her up on your behalf.
If you're using a phone, typically if you press and hold over the URL: it will allow you to copy the link. You then press and hold in the UKP message body to paste. If you're in the gumtree app, there should be an icon for sharing in which there will be a copy function.
