Good location to visit Vienna, with metrostations Praterstern and Prater Messe within walking distance. Quiet apartment, as it is situated to the courtyard side, not street side.
Everything you need is available. The big ventilator in the living room is quite useful as it can become very hot in summer... Many food supermarket in the neighbourhood.
Darkening curtains in the living room could be considerer for third and fourth guest who sleep in the living room. All in all, nice apartment, good location. We recommend it!
