The apartment is a nice modern (recently done up actually) place, with a generous amount of room, though best suited to lone travellers or couples.
The place is located about 10 minutes walk from Kaisermuhlen: Vienna International Centre U-bahn on an island area with the Danube river, old and new, flowing either side, and the area itself is nice and quiet.
Elisabeth is a kind host, and happy to help with anything if need be.
