Sandra is very friendly host and willing to help. She communicates well in English. Plus she is really hot (if it's important to someone). :) Sandra's place is well connected to the city centre (about 10-15 minutes with public transport), Westbahnhof (few minutes with a tram) and Schonbrunn (less than 10 minutes with a tram). The accommodations are as described, and it wasn't hard to find. My recommendations.
