Milena's place is just as shown in the photos and had everything we needed for our stay. It's very clean with great window light. Milena was quick to respond to messages and although she was out of town when we checked in, she stopped by to meet us and see that we had everything we needed when she got back. The location is excellent, close to everything but also far enough away so it's quiet. The location and building are very secure. Can walk to many of the main attractions and transit options are just a couple blocks away. The transit system around Vienna is efficient and fairly easy to navigate. We got a one week pass at the airport for less than 20 euros and made full use if it, travelling to all ends of the city. Can also take public transit to and from the airport on the pass, plus an extra 1.20 euro. The ride is about 20-25 minutes and the station is a 5 minute walk to Milena's apartment.
Would recommend staying here.
