Firstly I have to say the building is incredible. After seeing so many concrete apartment blocks in Bari it is a gorgeous, light diffused, beautiful entrance hall with a tall atrium. It made me happy each time I went home.
Apartment was spotlessly clean, stylish and super comfortable. Great bed, great sofa and dining area too. There was a small functional electric hob suitable for small meals and lots of plates and equipment. There are small grocery shops nearby and bigger supermarkets about 10 min walk away.
I would say stay here if you're visiting Bari as a base for other train trips around the area as it is about 10 min walk from the main train/ bus station. Note it is 20 min walking from the old town where there's more evening activity, restaurants, cafes etc.
The hosts were great and met me on time, and were really responsive to messages even early in the morning! Recommended.
