Jesus was a very good "host". No problems with communication or handover whatsoever.
The trip with the bus was just fantastic and one of the greatest vacations of my life. It's not in the description, but the bus was equipped with all the stuff you need for such a trip: table, chairs, glasses, cutlery, stove, towels, etc. The shower was very welcomed after the trips to the beaches and we got some envious glances from fellow beach visitors on the parking lot.
There were no issues with the police or anything the like, we were only warned once to not stay another night (which we didn't plan anyway).
Definitely the best way to discover Mallorca. Which is one of the nicest places Europe has to offer.

Thinking about getting a camping bus myself.
