Rosanna is extremely positive person! If we will go to Bari once again we will deferentially stay in her studio.
Old city is 15 minutes by walk from the flat, round the corner is really big and well equipped store with italian food :) the best gelatto in Bari are just round the corner around 1 minute by walk from the studio.
To the beach is around 30 minutes by walk but you can take bus number 12 from the bus station, which goes around 7 minutes straight to the beach.
Studio was really clean and you will find anything what you need there :)
I highly recommend this place to anyone who would like to stay in Bari in quite city center area :)
