In October 15 euros including electricity, there is no drain for the gray ones and there is no possibility to load water, you have to move with the camper towards the sports center and load it from the public fountain, for the black ones you have to go to the side of the bar and unload them in a well ..... if you do not have any needs you can do them a couple of nights, the historic center of Molfetta is about 2 km away and deserves to be visited .
