Serena took good care of us. The keys were provided by her nice aunt. Everything was handled very friendly and uncomplicated.
The house is really authentic - situated in the old part of Bari you can reach all the churches and sights by foot. 3 to 4 floors (if you count the terrace as well) makes the house an adventure itself.
The view from the terrace is really great. Everything was tidy and clean and we can definitely recommend "Earth-Sky" as an authentic italian stay in Bari. Mille Grazie for having us :)
