Hi there!
One tip would be to find some temporary accomodation with some "agriturismo". That is, kind of bed&breakfast; they are often priced something like 20-30 € per night. When I was in VA, some of my mates used to stay at "agriturismo Lalla" (I have no data for that, sry), near to BGY.
While staying in a place like that, you can wander around and find some suitable accomodation without relying on a blind choice
