Lisa-Maria is a great host and the place is great.
Great location with shops around, many ways to get around the city (the U1 is right there, but there are also good tram lines), and walking distance from the Main Station and from two great parks at Favoriten.
Also, the place itself is very complete, it has a well equipped kitchen, a full bath, and a big fridge. The mattress is comfortable as well.
Would recommend also for long stays.
