Hotel Erzherzog Rainer 
Star Service
Oyster
Star Service "Tourists benefit from the convenient public transportation (U-Bahn Taubstummengasse is around the corner) and a modest room count and equally modest restaurant serving schnitzel and goulash"
Oyster "In-house fitness facilities are also lacking, though the hotel does boast a traditional "wirtschaft" restaurant that is frequented by locals and guests alike"
