Returning (Barcelona)

Hello everyone,
I would like to get a feel from all of you as to live in Barcelona today. I am a Spanish national but lived and worked in UK for 30 years so really I am more British that Spanish and I am returning next year if I plug up the courage.....I am in my early 50's and with a career in Finance.

I would like to hear from you as I am a "tad" scared to leave everything I have come to call home behind and embark in a new adventure....

Thanks, Elena
