BePark - Parking Place de Turenne Saint-Maurice

Edit: after re-installing the App the pedestrian access worked as well.1 star less because of narrow stairs to get to the exit and no elevator, with luggage... pure horror.Many signs indicating the direction to BePark reserved spaces, but on level -2 just found four spaces three of them occupied, the neighbouring to the vacant one partially blocked by another car for the three days. Thus hard to open the door for the passengers as well or getting the luggage from the car's trunk.No clue where was the access to level -3??
