Diana's place is a really nice place for short and long stays. It is a high ceiling, authentic Viennese apartment. Diana is a really helpful and responsive host as well. I would love to stay there for longer, since it is at a great location. Not right at the center, which keeps you away from noise but still close to local shops and few touristy shopping streets. It is at waking distance to museum square and you dont need to go far for dinner, there are really nice restaurants around the apartment.
