This listing is a perfect balance between price, location, and value, and the host is just great. Much better than we expected.
The room is huge, clean, and well-lit. At first we had reservations because smoking is allowed, but we didn't smell any smoke, and the air actually felt quite fresh and the room smelled pleasant.
Clemens was abroad, but communication with him went flawlessly, responding to every message with no delays, giving us detailed answers and useful tips. We were welcomed by his roommates, who were very nice with us and showed us around the apartment.
The location is perfect if you want to be near the center, but still in a quiet neighborhood. We didn't hear any noise at night whatsoever, and the huge curtains helped us sleep through the early morning hours. Praterstern station is just 2 minutes from the apartment, and there are two Citybike stations right next to the station. We usually rode bikes to the center, but one time we even walked, since it's not that far. Definitely recommended.
