This is an excellent, spacious apartment on the 4th floor. There's lots of natural light. We stayed there for a month, loved the Gordon Ramsey-style fully-equipped kitchen, and enjoyed "the scavenger hunt" for the lights (you'll discover lots of them :D).
The area is also great, easy to get anywhere with the tram or metro, nice walks at Augarten, tons of shops and restaurants.
Vigo was a very friendly host providing us quickly with help when we had any questions.
