Hi Jane and David,
We went with Zurich the company suggested by polarisworld, we checked with our solicitor who suggested 3 other companies ( cant remember the namesright now) and although the costs were quite close Zurich just covered everything including 3rd party liability insurance up to 300,000 euro.
The premium for a 3 bed ground floor in the jardines was about 220 euro,hope this helps. this price was in june last year.
Regards Ken and Fiona
