OaseX is an anonymous and discreet laufhaus (walk-up brothel) in Klagenfurt, Austria, described as the number one in the city. The venue operates like a regular apartment building where ladies rent their own rooms independently. Residents are required to undergo weekly medical check-ups as mandated by law. Services without protection are strictly prohibited to ensure the safety of both guests and ladies. There is no bar or active solicitation, unlike nightclubs. The entrance is free. A presence board in the ground floor shows which ladies are currently available, and vending machines are provided for refreshments.
