We have used Airbnb for over five years and this experience easily ranked as one of our best. The house is built to a high quality by her husband and son, very well maintained, and sparkling clean. We had everything we needed and more. We cooked our own meals too and found the kitchen well equipped. We stayed for a month and our linens and towels were refreshed weekly. Angela is a great host and cook and we got to enjoy her cooking and produce from the farm. Although we only spoke English, we had no problems communicating with her (Google Translate was very useful!).
You will need a car, but it is very well situated in Martina Franca (15 mins to centre of town) and the region of Puglia. Be sure to ask her for recommendations of local restaurants as she has excellent ones to recommend.
We will definitely stay here again if we plan to revisit Puglia :)
