I been a few times, Mrs worked there for 7 seasons before we got together.
Totally chilled place (out of season) houses are expensive (very) but cost of living isn't extortionate because your spending is limited.
Its not big enough for us outdoor lads, I walked every footpath on St.Marys in 2 days ? I visited every off island there was a boat trip to and they are really a step further but you'd need a certain mindset to live there.
We nearly did, but we didn't get the job, with hindsight I'm glad really but if your into fishing and the sea, absolute bliss ?
Cheers, D.
