Very clean and an in an ideal location. The tile floor in the showers is more slippery than we expected; my elderly parents could've of used a bathmat to provide some traction, as well as a soap dish within reach (the only place to put items is on the ledge that is floor level). The interior building halls can be a bit dark (the apartment itself is very well lit), but nothing that a flashlight or phone can't fix.
Regardless, we'd highly recommend Arya's home. The apartment was spacious enough that 6 adults and 1 child co-existed without bumping into each other. Thanks for a great stay in beautiful Vienna!
