The apartment is fantastically situated in the heart of Vienna with a lovely view of the sunset and a great view of the city. The street is lined with restaurants and there is a Spar supermarket just around the corner from the apartment. There is a train station just a few minutes away as is a MacDonalds if that is your thing. Haus des Meers is 10 minutes walk from the apartment, MuseumQuartier is 10 minutes walk from Haus des Meers, which is 5minutes walk to Hofburg castle, which is 10 minutes walk to St. Stephen's Church....Along the way, you get to visit the high class labels lined up in a street. to top it off, Bolt taxi app offers very cheap taxi rides across the city.
Would surely recommend and stay at Felix's place the next time I am in Vienna.
