We stayed at Trullo Edera in June 2014. It is situated a few minutes drive from the local town, down narrow country lanes. The Trullo has been beautifully restored using traditional methods and is pretty, charming, well-equipped and very comfortable. Anna was most helpful and patient, answering all our questions and making lots of useful suggestions about where to go and what to see.
The area is lovely; we especially enjoyed Matera, and walking round the delightful "centro storico" in the local towns. Evening is the best time to visit, when the heat of the day has past. Not surprising that the locals choose this time for their "passiagata", and we spent several hours people-watching in the pavement cafés and restaurants. All in all, an experience "da non mancare".
