This was truly a top-notch experience. Alexander and Bettina live next door to the flat, and both speak very good English, which was nice for us. Bettina was on hand as promised when we arrived to let us in and show us the flat. Both she and Alexander were very helpful with recommendations and answering questions. The flat was lovely, so nicely appointed that you felt you were at home in Vienna. Everything from coffee to laundry soap was provided, and there was a Spar about one block away where we could pick up breakfast items or anything else we needed. The location was also great for getting around the city. S-bahn D stop was just at the end of the block, and the Karlsplatz Metro station was maybe a 10 min. walk. That put the whole city at our fingertips. We had a marvelous time and would happily stay there again.
