Yes I visited Alberobello to see the Trullia house I had heard so much about. They are listed on the World Heritage list and although it is a life ambition to visit most of this list, I know it will not be possible. But I shall visit as many sites in the countries I do visit in the next 10 years.
My Visit:
Being off season, I didn't expect many tourists and only found a few from the cruise ship, tour bus that stopped for a few hours. The balance of the 1 day I could stay in Alberobello, the streets were amazingly quiet. The staff at the "tourist shops" were always outside, cheery and very welcoming. They made you feel at home not as an inconvenience or as just part of their job, as in so many other "tourist locations".
I chose to stay in one of the traditional homes for the "experience" but what I did NOT expect was how kind everyone was: from the staff at the rental office and the stores to locals I met at the deli and other non tourist locations.
