Castellana Grotte is a really nice town - we had The best food, Italien food, we ever had on an Italien vacation in this town.
There isnt really ankom of tourists in The town, and this is both The best and worst about it. The best because its not ruined, The food is authentic and The people and surroundings are as Italien as expected. But as there isnt a lot of tourists, the town is a bit slow and not much is open really, so a week in The town, might be a bit to slow - it was to us anyway, but we had a car and could take some trips around, but a full week was still enough.
