Gerhard's unique basement accommodation totally exceeded our expectations as well as his open, friendly, welcoming communication. Once heading for Vienna again, We will definitely stay at his place again. I can bravely call his place our Viennese hideout. I hope this speaks for everything. me and my family felt like in some kind of adventure game. The lack of views of Vienna was perfectly substituted with lack of street noise and excessive light which made for perfect sleeping therapy. The equipment, including the sauna, was just enough. I really liked the ceramic set of dishes from Thailand. The overall atmosphere of a sensitively reconstructed industrial building was special. Thank you Gerhard for everything. We cannot wait to come back.
