Everything in the apartment was excellent. It is a surprisingly large space, particularly for two people in the city of Vienna. It was very clean and comfortable, and the kitchen was a great place to prepare and eat our own meals when we didn't go out to a restaurant.
Alice was a great host. She was very responsive and helpful in all cases, and even made a folder with recommended restaurants, attractions, and transit connections. And she made an obvious effort to make sure we had the basics before we arrived: soap, shampoo, towels, coffee, milk, etc. That was very nice.
One thing that concerned me a little before I booked was the location. I knew it wasn't bad, but I also saw several other available apartments that were closer to the city center. My opinion is now this: this apartment is extremely well-connected via public transit. Yes, you may be able to walk to some places from other AirBnBs, but this one has quick and easy connections to and from the airport, both major train stations, and many other places of note in the city center and elsewhere. No matter where you stay, you'll probably need to take public transit most of the time, and this apartment is exceptional in that regard. Also, I went for run a couple of times, and nice running/biking paths and parks are also nearby.
All in all: I'd stay here again without any concerns at all; I highly recommend it!
