Pros- Great location, near restaurants and mrt. Easy self checkin and out. Window view of street is nice, ceiling is high and feels spacious. Easy to make self feel at home fast. Nespresso machine is convenient in the morning.
cons- Walls are thin and occasionally neighbors party into the night or blast music early in the morning. Shower water heater is erratic and needs to be constantly readjusted during shower to get adequate hot water.
Still, the pros far outweigh small cons, I would live here again if I came back to Vienna- location, view, and spaciousness is good
