Isabella's brother waited for us and was very nice and welcoming. The place was clean and cozy, exactly how it was described. The location is good and the atmosphere in the house as well. The only issue was that the bed was creaking too much. :)
In the shared kitchen there is a shelf with books - travel guides and maps, which were very useful, but the best thing was the hand-made book "What to do in Bari" with travel advises, information about train and bus schedules and history of the main attractions in the city. I guess it was prepared by Isabella and indeed this was a lovely surprise. :)
