This is a brilliant flat in a great location : very comfortable, lovely views of Stephansdom, good access the the centre of Vienna, good nearby restaurants, good shower (essential !), well-stocked kitchen, very quiet - in other words everything you need. The only thing to be aware, as others have commented, is the four floors and no lift, but if you're even moderately fit this won't be a problem. We had a wonderful stay here - can't recommend highly enough.
