This is an absolutely beautiful, modern studio apartment, located close to everything in the centre of Vienna. The apartment is small (25 m^2 is a guess), but stylishly decorated as though it were a boutique hotel, and very comfortable (also the bed). The hosts were very welcoming, and made the arrival and departure formalities easy and quick. I couldn't be happier, and will be glad to stay at Gerhard and Nicole's place again in the future.
