We stayed in Osnat's apartment for 5 days and really enjoyed it : it's super clean, nice and there is absolutely no noise at night. It's 10 minute walk to the nearest subway station which is very convenient, but you can also go for a walk, eat or shop in the neighbourhood and of course walk to the Prater or Augarten. Osnat welcomed us really well and gave us some ideas on where to go. I definitly recommend it.
