You will obviously rent a car if you are in Bari. So do not let the distance be a deciding factor because you do not know what you are missing out on . The trulli houses are only about 15-20 mins drive.
There is nothing in the area, it's a quite village, but the nearest village is only 10 minutes drive ( you can go there for lunch/dinner) . What can I say about the house?? Each and every corner of that house is so well put. It's beautiful, cozy, clean and comfortable. We met Anna and her son, such warm people. Anna bakes some mean tortes and tarts! You have got to try them.
