Daniela's apartment is exactly as described. Cozy, clean, and well-furnished. What makes it amazing is its location. You're within 5 mins walking distance to a metro station, tram station, and 2 supermarkets. It has lift access, but is only 1 floor up so I usually just used the stairs :)
Also, Daniela is an amazing host. My luggage got lost by the airline upon arriving to Vienna, and I had to give the apartment phone number for contact as I didn't have a local number. Daniela was amazingly helpful in updating me about the baggage, and also giving me tips about good times to do shopping in Vienna. My trip would have been a lot worse without her!
