I stayed with my mother in that flat in Vienna. The flat is situated near to the tram stop and metro line U6. It takes around 5-7 minutes on foot to reach the public transpost and 10 minutes to get to the opera Volksoper. The connection to the city center is perfect, all the main sightseeings can be reached very fast and easy. The communication with Charly and Josef was nonproblematic, nice people. The flat is equipped with all one may need: washing machine, hair dryer, iron, dish washer, oven, all stuff for the kitchen. I liked the old-fashion style furniture a lot, very beautiful, in perfect condition! I definetly recommend the flat and I would be glad to stay there again when I am back to Vienna :-)
