I spent 3 nights at the Casita, the house is very well located, not far from The Bari Centrale Station, the old town and the beach, so everything can be done on foot.
the house was perfect, it was very clean and very well equipped. the AC was a huge plus. The area is also very calm.
The Hosts were absolutely delightful, Maria Pia was very accomodating, she adapted the check-in time to suit my needs. she also suggested restaurants (which were amazing recommendations). she also checked-in on me making sure I didn't need anything else.
The Casita was a great choice for me. Highly recommend it to people traveling to Bari.
