I highly recommend Tina’s flat in Neubau. It’s a very special place in one of the nicest neighborhood of Vienna. There is everything you need to cook, a nice bathtub, real cool interior design, a washing-machine, etc. The area is great too, packed with nice restaurants and shops. It’s only 15 minutes away from the historic center and 10 minutes away from the bus stop going to the airport. There is also public transportation (bus, tram) 100m away. Tina was a welcoming host and her recommendations were precious. I would definitely stay at this apartment again.
