Not knowing Vienna I thought the apartment was in a great location, the best of old vienna was on the doorstep and just diverting down some side streets you can find quaint bars that seem only for locals.
The apartment itself was evidently cheap "my partner booked it" compared to other offers of airbnb apartments in the area, its basic but serves its purpose it would be better however if just a few little improvements could be made to make it slightly more homely; good pillows would not go amiss and just a bit of coffee or tea on arrival instead of having to go straight out and purchase it would be nice but having said that great place and would come back.
