Hi Sarah,
Welcome to the forum, you will find the answers to most of your questions here as we have, if you click the search facility at the top most topics you want to ask about will I am sure have been asked already and this should help.
We went to Calis for the first time last year and loved the place, the people, the sunset so much we bought an apartment and can't wait until we are back there on 27th August.
Good luck with your property hunting.
Regards
June
