As a couple visiting Vienna for three days, the flat was quite comfortable, with a large main space and very close to several means of public transportation (a few streetcars just down the road, 7 minute walk to the metro and train). There was a city bike station just down the road as well if you plan to see Vienna by bike! Be aware, the shower is only separated from the main hallway/rest of the studio by a shower curtain and the toilet is separated by an accordion door. It was a great base for a short stay in the city.
