The owner nicely contacted us to provide directions from the airport before our trip. It would have been nice for them to give us a map of the city, but we found one easily enough. A free, very Austrian, breakfast was served every morning. It was very good, and easily would cost 8 euros at a nearby restaurant. Free WIFI was provided in the TV room, but not accessible in the bedroom—consistent with website description.
The room was exactly how it was pictured online. There was a sink, hair dryer, a desk, chairs, and 2 closets. The beds were comfortable and clean. The showers and toilets were separate (which was nice). The Pension even provided clean slippers for us to use. We never had to wait to use either the toilet or shower. They were clean, however the step up to enter the shower, without any supportive bar, would likely be difficult for some people. There was not a lot of noise, either from the street (which our room faced) or the other tenants.
The Pension was a ~5 minute walk from a good metro stop, and a pleasant ~20 minute walk to the city center. It was a safe area which we comfortably walked at night.
Payment is in cash, but the owner was nice and provided a receipt even before we asked for it (which at a lot of places is unusual). Note: payment times are restricted to breakfast hours (8-10am), unless another agreement is made. Although friendly and prompt, the staff was not very engaging, quite business like.
Overall, it was a great place to stay in Vienna and we would definitely go back.
