In general it was an ok stay (perfect address for visiting Vienna), BUT we will probably not return and not recommend this place. There are seroius setbacks: The sound proofing to the neighboring flat is close to non existant - NO privacy - we had to use ear plugs. Nowhere to hang coats. No iron or -board. One (1) washing mashine and tumble dryer to share with all other airbnb tenants in the apartmentbuilding ... placed in the deep basement (quite spooky). The equipping of the kitchen was really below basics (no toaster, no deep plates, no serving bowls, no cutting board or a simple can opener. And there is no exhaustion, which means steam and cooking smell in the whole apartment after prepareing meals!
On the positive side: Nice bathrom (not well ventilated and no shelves or cupboard to place toiletries), great bed (but no topblanket or an extra sleeping pillow), free WiFi (that is if you are ready to create a profile with Freewave and accept 3. party ads for 1 year) and nice balcony.
