It really depends where in Whitton the house is.
If it's south of the rugby ground/near Ivybridge, or near Mogden, it can be smelly at times, but if the house is in Whitton proper (closer to the station). Thames Water have invested millions over the years to improve the air quality, so I don't think it is anywhere near as bad as it was 10-15 years ago.
I grew up nearby, and my impression of Whitton was that it has an older/retirement feel to it. Of course there are younger families and schools etc, but it has an older, white demographic. The high street reflects that. It's mostly independent shops, though there are a couple of coffee shop chains. For proper shopping you'd need to go to Kingston, which is only 10-15 minutes drive away and huge. I love Kingston shopping.
Whitton also benefits from having semi-fast trains into Waterloo (stop at Twickenham, Richmond, Putney, Clapham Junction and Waterloo), so it only takes about 30 minutes to get into town if you time it correctly.
Good things are that you are next door to Twickenham, Richmond, A316/M3 are also on one end of Whitton, so handy if you need to go South. M4/M25 and the airport are also nearby so it's well connected.
I don't think "Hounslow thugs" have much interest in Whitton, there's really not a lot there for them! If you need the tube, and are feeling brave, Hounslow has 3 TfL stations for you to choose from, though the easiest to get to from Whitton is Hounslow East.
