We enjoyed our stay at Maureen's place. Maureen's very responsive. She picked us up from the train station and gave advice on luggage storage after check-out. The apartment is 3 to 5 minutes away walking distance from the train station. Easy access to metro, bus, and citybikes. Downhill street toward Karlsplatz (10-15 min walk). Kitchen and bathroom are well-equipped. There is stand-alone AC, but the weather was nice enough that we did not use it. Furniture in the bedroom is a bit oversized, but definitely enough room for luggage. Multiple supermarkets around the corner (although they all close relatively early at 7pm). We highly recommend Maureen's place for Vienna sightseeing.
