Hey Andrea,
Don't want to sound like a wet blanket but the chances of finding a villa on anything less than a 1 year lease are virtually zero, and even if you did the price would be incredibly high compared to the DAGOC offered accomodation. All the new DAGOC starters are moving into the provided accomodation unless they already have friends out here who saved them a room. On a positive note, the DAGOC flats are apparently quite nice - 2 bedrooms, 2 bathrooms fully furnished, no contract or deposit. They just opened up the 2nd building last week, and I think they're refurbishing a 3rd block for all the people coming in June/July. Don't worry about the two weeks in the hotel though - if you put your name down for DAGOC accom. you will be able to stay in the temporary accomodation until they have the permanent flats ready.
If you want any more info drop me a line at [email protected]
See you soon!
Andy
