Their website says it's in the heart of the entertainment and leisure areas:- http://www.thegeorgemalta.com/

Paceville is THE pub and club capital of the island probably not the ideal choice for the older couple as it is party central, it is not far from St Julians though.

How long to walk to Julian's please

Its not a long walk you are only something like 10-15 minutes leisurely stroll.

We stayed in St Julian's when we went to Malta right on the doorstep of Paceville, but when we were actually on our hotel we could have been a million miles away, it's just that when you go out doors it's all a bit in your face in terms of nightlife.
