This is one of those rare Airbnb apartments where the place actually does look exactly as nice in reality as it does in the pictures! I didn't get a chance to meet my hosts in person but they were very communicative and efficient with replies before and during the trip, which I greatly appreciated. As others have mentioned, the outside can be noisy especially in the summer with windows open so earplugs might be good if you're a light sleeper but this didn't bother me much. The apartment is very clean and modern, and also well-located (3 minutes to the closest bus stop and only a 10-ish minute walk to the subway station, and 2 minutes from a decently-sized grocery store). I'd definitely stay there again if I'm visiting that side of Vienna in the future!
