Susanne was a lovely person and this is a lovely place! It was absolutely perfect for me, my wife, and our two year-old son. I was a short walk from the conference center and the flat is literally across the street from the Messe Prater metro stop. The space is very well furnished (loved the high ceilings!) and couldn't have been more convenient for our needs. I would enthusiastically recommend Susanne's hospitality, and hope our travels bring us back here someday!
