Sorry for getting back to you late - hope it's still available!
It's a sound area and transport is alright depending on where you are. The #23 bus takes you to the stop over the bridge, and the Stadium of Light is about a 10 min walk from there. There's a #4 bus on Durham road that gets you close to the Stadium, too, but again it depends on where you are in Thorney I suppose.

Seen an OK looking AirBnB but I need some location info.
It's in Thorney Close, OK area? Links to and from the stadium?
