We enjoyed our stay in Vienna. Though Osnat was not in Vienna during our stay, she arranged for someone else to hand over the key to us. The place was clean and the bed and sleeping couch were comfortable. From the apartment you can either walk to the centre in 20-25 min or take a tram or metro (the nearest metro station is about 8 min walk away). We recommend to drop by Kaffee Bar Balthasar, nearby Nestroyplatz metro station, in the morning for coffee and breakfast.
