This place is just perfect. I lived in Vienna for a few years, and I was looking for a place near the city on the underground line, but not in downtown. This place is that and more. The location is right next to the Kagran station and subsequent mall, but not so close that it is loud at the apartment. It is walking distance (like 2 minutes max) to at least two grocery stores. You can get to downtown Vienna in less than twenty minutes and one underground train ride.
The apartment itself is absolutely perfect. Sparkling clean and comfortable. It has everything you could need - big comfy bed with lots of blankets if needed, comfy couch with TV and channels, full kitchen with 4 stove top burners and an oven, nice big bathroom that even includes a washer.
The hosts were constantly available in contact with us to make sure we had what we needed. Check in and check out was easy.
I couldn't recommend this place more.
