Below is a cut and paste from Mad Cool english speaking fans FB page. Seems to confirm new location but not sure if last sentence is from the reply from Mad Cool or the authors take.
After my mail regarding New Location and Hotels nearby I got this answer:
The location of the venue is in the Villaverde area, in Laguna Dalga street. As for the displacements/transportation, there are train and subway stops nearby, as well as several buses.
And as always we will have shuttles to the center of Madrid.
More detailed information will be published later.
I needed to add, that public transport doesn´t drive after the concerts and the organisations with the Taxis/ubers didn´t work either... I think, we´ll skip this year...
