Basic hotel, but that was what we expected.
Nice and light design of the interior, feels clean and well maintained.
The room we had was clean and felt quite large and airy, the bed was firm but comfortable, the AC was adjustable per room and worked perfectly, shower had all the hot water you can wish for and toilet and sink worked as you'd expect.
Transportation options are good, you've got the U3 line around the corner, the Vienna International Busterminal a short walk away and St. Marx station with the S7 to the airport is just a couple blocks away.
The breakfast is basic with no hot food but perfectly adequate, fresh and of good quality. There is a grocery store next door, a gas station with a convenience store that stays open late across the road and at Gasometer there's shopping and restaurants.
We had a great stay and I think you'll have a hard time beating this for value.
