We stayed in this AirBnB over Christmas with our two daughters, and it was absolutely lovely and made our holiday very special. The apartment is gorgeous and has so much character -- floor to ceiling windows, chandeliers, decorative frosted glass door panels, decorative mantels, lovely hardwood floors, and very nice bathrooms. The location is wonderful -- just a quick minute walk to the Graben and cathedral, Metro etc. There is also a fabulous grocery store just steps away.
As others have noted, it can be loud in the morning, the floors are very squeaky, and the bathroom showers leak some water on the floor. None of those things really bothered us much, though, because they are minor and everything else was so fabulous. I also had trouble with the washer/dryer, but Birgit was helpful.
