This place is fantastic. It is very clean, and it has all the amenities you need (and more). The best part about it is the location. It is along the Danube in the Innerestadt. The airport bus station is right outside the door of the building, and the U-bahn station is a very short walk (5 min or less). From there you can go anywhere; we took it to Schonbrunn Palace, Belvedere Palace, and the Hauptbahnhof (main train station) where we took a train to Salzburg for a day trip. It is a 10 min walk from Stephansplatz where St. Stephen's Cathedral is located, and it is the geographical center of Vienna. Everything was in walking distance, which was nice, because we came across so many lovely Christmas Markets. We had 4 people in our family, so we used the 2 beds in the main bedroom and a sofa bed in the living room area. The one bathroom has a large tub/shower and a sink, and the toilet is in another room in the hallway. This was convenient, because someone could use the toilet if the shower was being used, and vice versa. There were a lot of nice touches in the apartment and extras, including an espresso machine. I would definitely recommend this location while staying in Vienna.
