I used to live near Barnstaple, and now live in North Suffolk. Just a few things to be aware of down there. It's very green and lush because it rains an awful lot! especially compared with dry old East Anglia.
The main shopping areas for a big department stores type shopping trip are in south Devon, Exeter or Plymouth, so quite a long drive, or train journey. It's a long while since I was there so there may be some new centres now, similar to Lakeside?.
In summer the roads are full of holidaymakers. It's hard to get anywhere fast. They also clog up the shops and pubs etc.
We found that friends and family were all wanting to come and stay, for a holiday, which is lovely, especially when you're retired. It is a long drive back to the south if you still have friends or family you want to visit.
Having said all that, it is such a beautiful area, and I found the people friendly and warm. I used to love walking on the beach in winter.
