This is a little pearl, newly renovated. Despite the 1900s theme the kitchen and bathroom are fully up to contemporary standards (as are the electrical installations with plenty of outlets) and it is in a very quiet area (except when the Torah school next door lets the kids out to play, but you should really be out exploring Vienna at that time of day).
It took me a few tries to find the best connections for public transport, but you do have a bus 50m away that lets you change to tramline 2 and U-bahn 1.
