We liked the spaciousness of the apartment, the furnishings, the living room/dining room, the big main bathroom, and especially the colours. The toilet is separate and close to the front door, near the kitchen. A little far from the bedroom, perhaps. The location suited us well in a quieter, residential neighbourhood within a 20 to 30 minute walk to downtown Vienna. There's a great market about 5-10 minutes walk away, at Carmelitergasse, where we bought some great fresh fruit and veggies, and ate at a great vegetarian/organic restaurant - has THE best curries. Underground public parking here is the closest parking to the apartment - if you have car. No public parking on the streets in this neighbourhood. Otherwise, there's a convenient subway station about 3 minutes away.
If you are planning to make your own meals, the kitchen was small and awkward, and not well equipped. It would be fine if you're planning on eating out though.
The whole apartment could have been cleaner! If the host is cleaning it himself, we recommend he gets a professional cleaning service in to do that for him. Wifi was fine but we had a few problems getting connected, however the host was easily accessible by text/phone. A good place to stay for the price.
