The apartment is perfect for 3 people - there are 3 separate bedrooms with comfortable beds, a bathroom and a small kitchen. The location is nice - the building is located right next to a subway station so you could easily commute from the airport and to the city centre. Two of the bedrooms are facing a main road and it could be quite noisy if you sleep with the window open. Overall great apartment for a very reasonable place. I definitely recommend if you are visiting Vienna for a few days.
