Yeah there are 24 hour shops and garages, traffic isn't that bad at all, no more than any other small city. Never takes long to get around in the city centre
Lovely place when the sun's out, city centre is pretty big for shopping, it's all in one place and everything's open
Your also right on the edge of dartmoor and only have to cross the bridge to Cornwall, scenery is lovely, I think it's a great place to live
As with anywhere there are sh!t areas but there all out of the way to be honest, you can easily never see them. There are lots of small towns within a few miles of the city limits which are very nice like Ivybridge and south brent etc
