Airbnb - Vienna
Modern City Apartment Schwedenplatz - Three Nights
Ok, so the great news, is these apartments are located in the perfect location to explore Vienna.
However, if you're staying more than two or three nights, you'll find them too small and not well equipped to cook or work.
None of the rooms are the same (no drama with that), the Airbnb listing says all rooms are the same fit-out and size.
The floor plan below shows that none have a balcony and the preview image on Airbnb is very misleading. The bathroom is tiny.
