It was really nice staying at Sibylle's place. She is a very warm and friendly person, who loves a good conversation. The apartment was really convenient to reach and one can walk to the city centre easily. Though near to the city centre, the apartment is located in a very quiet area. The train station is 5 -7 min walk from her place and there are also some restaurants nearby. There is also a beautiful park nearby. I highly recommend her place if one plans to visit Vienna.
