I really enjoyed staying at Antonella's air bnb. It's a beautiful apartment, I stayed roughly a month, the apartment is brilliant! I had everything I needed and Antonella was on hand to help with any questions I had. Antonella has put a lot of thought and lovely touches into the apartment for her guests. I really loved it. She is a great host and very friendly - you will be in great hands! I had such a great time, I will defiantly be going back.
Castellana Grotte is a beautiful town, has a great fruit and veg market on a Saturday, the folks are super friendly, make sure you take time to explore the town, there are some beautiful buildings, shops, piazzas, and restaurants. I also used the buses to go to Bari, Monopoli, and Polignano a mare. Make sure you try to talk with the local people - I made lots of friends! I miss it already!
