The location is not exactly central to the city, but it is in a perfect spot for tourists, near to schönbrunn castle and a short transit to the city. There's a supermarket, cafés, and everything you need in walking distance. There are other people living in the apartment, but they keep to themselves. Upon arrival, the way to enter the apartment seemed a little scary, but it was perfectly safe. There are two flights of stairs to her apartment. Everything is as pictured, and she approved our use of the clothes washer. A warning that there is no lock on the door to her room, so you cannot lock your belongings, but her roommates are trustworthy and nothing went missing for us. (The apartment itsself automatically locks though, so no worries there). I never had a chance to meet Sandra, but she gave me instructions on how to enter and was always responsive with any questions. The wifi was fast. Overall, it was an enjoyable stay and I would recommend her place to stay for vacation!
