Room wanted within short distance of West Swindon

I am 62, recently widowed and have to return to England from Bulgaria after 14 years. I'm looking for a room, preferably in a family home near my son's family in West Swindon. I'd be happy to help out with animals children and garden. I'm not too fussy about amenities but would like to be near a bus route as I won't be able to afford a car. I will have to claim benefits as I have no income (the reason I'm coming back to the UK) so I would need Housing benefit. I'll be spending as much time back in Bulgaria as the benefits system allows, so for some of the time you would be paid rent without the bother of a lodger.

I have a flight booked for 21st October but will be spending the first couple of weeks with family, but I would really like to have a place by mid-November at the latest.
