The flat was wonderful! Our stay was short, but this is a place you could easily be comfortable for a number of days. It was nice to be able to clean all our clothes after touring various cities/countries for the previous 12 days. Christian was super easy to communicate with and he has done a wonderful job with his flat. Like many places in big cities, it can get a little loud at night. Christian has double-windows that do a good job keeping it quiet, but if you are a light sleeper, bring earplugs. The flat is easy to walk to from the U-bahn, and there are a couple of grocery stores and many restaurants very close by. I would stay here again...the flat is a great place to feel like home for a short time in Vienna!
