Ines was a perfect host very friendly and welcoming. She explained to us where to find all the important things around the flat. The location of the flat is really good. Very close to bus, train station, supermarkets, even a organic market and restaurants. Don't miss out to go to the restaurant called "Himmelblau" but for breakfast consider to make a reservation. The penthouse is exactly as described and as on the picutres. Very spaces, clean, comfortable beds and a roof top terrace with nice views of Vienna. I would definitely stay there again when coming back to Vienna. Thanks Ines for everything!!!!
