The community has insurance, but you need to insure your own appt (the inner side) and the contents. The company we used is very good: Spanish and English conditions, 24/7 support and they fix the things at their costs so you don't to organize it yourself.
Price will be between 160E and 190 Euros per year for a two bed apt. depending on the value of your contents.
The contact we have speaks very good English and is very efficient. She knows the Don Juan complex by now so she doesn't have to ask you all the questions again.
PM for more info. EOS doesn't like advertisements so I refrain from it.
