Modern City Apartment Schwedenplatz - Three Nights
Ok, the great news is these apartments are in the perfect location to explore Vienna.
However, if you stay more than two or three nights, you'll find them too small and poorly equipped to cook or work.
None of the rooms are the same (no drama); 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.
