This apartment is incredible. It's an unbelievable value with easy, quick connections to the airport, main train station, and the city center (>10 min to the train station, 15 min max to the city center via the u bahn). While Ines did not meet us there, she sent someone to greet us and show us around the apartment, and the two of them were very helpful and responsive. The pictures of the apartment and its view are all accurate. Private elevator is great.

However, the second bedroom (the white one with the slanted roof) does get very hot in the morning, as the windows trap the sunlight - and we didn't see any obvious AC, though we didn't need it, given the weather.

Regardless, we would stay again the next time we're in Vienna, and you should too.
