Ariella's place is a fine value-for-money place to stay in Vienna. It's well-located — 3-4 minutes walk to the airport train and metro station and just a littler longer to the Vienna's Ringstrasse, it's spacious, it's situated on a fairly quiet local street. The amenities, decoration and furniture are a bit outdated but that's not much of a problem. We had a couple bathroom issues (the sink was slightly clogged and the water mixer in the shower wasn't very responsive usually just maintaining average warm temperature) and there was no extra toilet paper and soap. Also keep in mind that there's no washing machine (that is mentioned in house description) which might be important to some travellers.
All in all we had a good stay but nothing special.
