I loved Isabella's apartment. It's big, bright, spacious and clean, and exactly like stated in the description. I loved that we had our own bathroom, even though it's a shared apartment. I also really enjoyed the big terrace, where we had breakfasts.
I made daytrips around Bari the whole week of my stay, the main railway station is less than 10 minutes of walking away, so the apartment has a perfect location if you'll be in anyway depending on the public transport.
I didn'meet Isabella personaly, but I did meet her brother Franco, who was really kind and made sure everything was OK during our stay.
I would love to stay here again, if I ever return to Bari, great place!
