Excellent place to stay in Vienna - especially for couples or one person.
It's a studio but that's misleading because the separate kitchen and walk-in closet make it feel much bigger than that.
We stayed for about a week during Christmastime and found it to be perfect - great location next to one of the major train/metro stations of the city so you can get absolutely anywhere in the city easily and you can also walk to the center in about 30 minutes if you prefer.
Grocery stores and restaurants are abundant nearby and the metro station is also a mall (there is another mall about 10 minutes walking with H&M as well).
While the apartment is close to everything, it's also quiet because it's located on a less busy street one street past the main street that runs in front of the metro station.
2 things to note:
1. There are stairs and there's no elevator - no problem for us but may be an issue for some.
2. The bed is super FIRM. I like it that way but my partner isn't as much of a fan.
Beyond that I can't think of a better place to stay in Vienna for a week, especially for the price. Cozy is a great way to describe it.
