We stayed for about 5 days here and had a very enjoyable experience. It's close to a supermarket and a short walk from buses, trams and the metro. It's also very close to a great path for running/walking along the river which we enjoyed.
The building has a lift (a bonus!) and is in a nice, friendly and quiet neighbourhood. There are cafes and restaurants closeby as well.
The apartment had lots of space, fast wifi (great because I needed to do some Zoom video calls for work), and also two air-conditioners! There's a washer and dryer which was a bonus as well and the bathroom was stocked with lots of amenities including a separate toilet. The kitchen was also stocked with all utensils etc and all that we needed. There's no microwave but this wasn't an issue for us.
Our hosts were also very friendly and welcomed us upon arrival. A lovely stay in Vienna and I would highly recommend this airbnb for anyone hoping to visit Vienna!
