The apartment is spacious and is perfect choice for families. We stayed two nights with three kids and loved it. Two huge bedrooms and a sofa bed in the living room. Everything is clean and new. Has all the amenities you need. The location is great - close to grocery stores, Prater park and the subway station. Though central, it is not noisy. There is a free parking on the street from 22:00 to 9:00. Plamen helped us with instructions for parking during the day time hours. Could check in and check out easily and quickly. Would recommend warmly!! Good starting point to sight seeing in Vienna. Will come again when we visit Vienna again!
Just a small note - few stairs you need to consider going up to get to the elevator. not a big deal.
