Great
The guide (I think his name was Alberto?) was incredible - he held the tour in English, German and French, as not everybody spoke English. The tour itself was okay, it is important to know that it is NOT a walking tour but with a mini-bus. The view from the miradouros were incredible, the village nuns-valley however is not very intersting. It's a good tour if you don't have a car and want to know a bit about the island.
