I spent 9 days in Dan's appartement and I enjoyed it. Perfectly located at 4 minutes from Schwedenplatz (downtown Vienna, near the bus station from/to the airport), clean and practical, safe and quiet, with a microwave + kettle + little tabletop fridge. It is not large, but large enough for two for a few days. Dan has been very helpful with all questions I had, advise and organization. I recomand this address.
