We did not meet Ms. Blanckenstein, however the house manager Alin Popus was really helpful. The house is located in the very charming 2nd district right next to the canal with its chilled out cafes . The apartment it self is spacious with a big lounge, high ceilings, a separate bedroom and a small kitchen. Overall our experience was very positive and we would highly recommend the place anyone planning on coming to Vienna! :)
