Michael's place is a stylish, modern apartment, very secure and very handy to station, if that is required. There is a Hop on Hop off bus point at the station and the Belvedere, which is a 5 minute walk away and the station itself is like a shopping centre with lots of little eateries and supermarkets. The apartment complex offers free coffee and is very quiet. If you want to be handy to Wien Hauptbahnhoff, you probably can't beat it.
