The place is spacious! While not in the city center, it's right above the Reumannplantz subway, making it easy to get into the city. As previously mentioned, Google Maps is terrible in Vienna so definitely download the Qando app. Costas was out of town but his friend was welcoming and helpful and accommodated my evening arrival. I had no problems with the place, but a couple of notes for light sleepers: as in much of Europe, the place gets very bright very early in the morning (even with the blinds it was bright daylight at 6am). Also, the beds aren't the world's comfiest. Still, all in all, good value for the price.
