Leo is a gracious host who made us feel most welcome. He met us at the flat and gave us tips about the neighborhood, including restaurant recommendations. There's an excellent Thai restaurant right in the building. The apartment seems brand new. It is charming, comfortable, clean, and quiet. The walls are so thick that we didn't hear any outside noise. The bed is one of the most comfortable we have encountered; we slept very well. Plus--a first in our experience of Airbnb--sharp knives in the kitchen. The building is in a safe, residential area. The 57A bus stop is right outside the building; the 57A takes you into the center in 5 minutes. There you can catch any of the trams that run around the city center. You are also about a mile from the Westbahnhof and closer than that to the metro. Also walking distance to the Naschmarkt. Leo's apartment is an ideal spot for exploring Vienna, and Leo is the perfect host. We highly recommend Leo's apartment.
