Have you ever heared about how houses are beautiful in Vienna? Watched a European movie and see how their properties are well designed? It is an opportunity to experience it. Everything was amazing from the fantasticly chosen furniture to Kilmit's portrait of The Lady in Gold.
Nevertheless, the place is just a one thing - the other is basically the extremely kind couple (Daniela and Peter). I am not exaggerating if say they made the trip 10x better.
