Facilities are certainly a bit dated - but the friendlyness and helpfullness of the staff was simply outstanding. I guess this means: let's get BER ready to go with nice new lounges - keep the staff!
Considering the organization of TXL (multiple gates and several wee terminals) the location (before security)is reasonable. This lounge has a great variety of drinks 🍹 (inc beer and other spirits).
Quite "sketchy" lounge but -at least- pretty calm. Free wifi. Decent drinks. Poor food. Friendly staff. The fact that it is before security/passport control: a handicap.
