The apartment is located in a fantastic neighborhood (4th district) with many restaurants, shops (there's a lovely bookshop at the same address), markets (Japanese market, Naschmarkt food market), galleries and a major subway station (Karlsplatz - two stops from Hauptbahnhof). It's a 10-minute walk to the State Opera. Communication with hosts was smooth. They provided good restaurant suggestions in the immediate vicinity of the apartment, places I wouldn't have discovered on my own. After check out I was able to leave my luggage with the hosts in the same building which was extremely convenient. The apartment overlooks a busy street so it was a good idea to bring earplugs. There is a lift in the building and the apartment is on the 4th floor. I was happy with this Airbnb experience and would stay here again.
