...probably the reason for (only slightly) lower prices than in characterful Pinner. There is a good mainline service to Euston though and Pinner is a short drive away if you can afford the daily parking fares. I wouldn't want to rely on the local bus service to get somewhere on time. Access to central London is good, and M1, A41, M40, M25 are an easy drive away.
Through traffic gets bad at peak times so it's best to live off the High Street. The High Street has everything you need, including a multitude of good restaurants. I suppose the shopping/entertainment centre would be Harrow, although Watford, Uxbridge and Brent Cross offer good alternatives.
There is a definite feeling of suburban wealth and security about the area yet also a variety of accommodation options. My only complaint would be the lack of a good local pub.
