If you have a look for example on Google maps, Canley Gardens is the area bounded by Canley Road, The Riddings, Bates Road, the railway line and Rochester Road. Strangely Beechwood Ave isn't usually considered to be 'Canley Gardens' but is nearby.
It's a very 'leafy suburb' of Coventry. Nearly all the houses are detached or bungalows. Only a sprinkling of semis.
