We spent a week with our 15-month old twins and the apartment was perfect with a big (play) room and useful equipment (2 cribs, 2 high chairs). The apartment is very well located in District 4 at the junction of Districts 1 and 6. The Naschmarkt market is nearby (visible from the window) and you only need a quick walk to get to the Opera and Albertina. It was clean, well equipped (you can bring the wifi with you anywhere in the city), and pretty big. Communications with Eva was always fast and efficient. The elevator was useful, although the apartment is located only on the second floor. It was not large enough to contain our massive stroller (Thule Urban Glide 2) when open, but was ok when folded. We would definitely come back!
