This apartment is beautiful, spacious, and well equipped! We particularly enjoyed eating dinner on the huge terrace (and the kids loved watering all of the plants). Angelo and his wife are great hosts. They were very easy to communicate with, very helpful, and they even left us some delicious fresh cherries and figs. We stayed for 3 nights so we could explore some towns/cities around the area, and the apartment was perfect for our family of 4. It is kid friendly but there are a lot of small fragile items in the house that would need to be moved if you have a curious toddler.
The apartment is well located, with a bakery/pizzeria, butcher, and supermarket within walking distance. It's not far from Bari, and we visited Polignano a Mare, Matera, Grotte di Castellana, and Alberobello, all less than 1 hour drive from Cassano. To cool off in the summer heat, we recommend Cirie Agriturismo, just one km from the apartment. There is a great restaurant and outdoor pool (bring your swimming caps).
Thanks Angelo!!
