Although the apartment is a bit quirky, its location is quite convenient, and it has plenty of space.
There is a metro stop immediately outside the entrance to the building and it is only a ten-minute walk to the Praterstern train station from which there is direct service to the airport for under $5.
There is a major amusement park immediately adjacent to the Praterstern train station.
There are plenty of convenient grocery stores located within five to fifteen minutes from the apartment.
One thing to keep in mind is that the apartment is a four-floor walkup, potentially an important consideration if you have any type of physical disability or a lot of heavy luggage.
Internet service is quite good, and the washing machine works just fine.
One last warning -- even on streets with no signage or payment machines, you must pay for parking. If you do not, the fine will be about $50, including a service fee to pay it at the post office. If you plan to park a car, either find a lot or get advice from a local regarding how to comply with the rules.
All things considered, this apartment worked out nicely for me.
