This lounge is for departures outside the Schengen section.  It has good facilities of charge one's devices with a choice of adapters.

Adequate seating facilities are available.

A food buffet with a selection that is expected in this type of lounge; but the food was mainly Indian with little Austrian cuisine on offer. 

For an international Business Class Lounge the wine selection was clearly suboptimal, but the selection of spirits was adequate.

The glassware was adequate. The staff was friendly; there were no boarding announcements made. The Senator Lounge had a shower.

Overall a bit underwhelming for a lounge catering for intercontinental departures, but just adequate.  March 2019.  3/5
