Gary was very helpful for the entire trip. We got clear directions to the apartment, and we had no problem getting into the flat. The house lady was there to meet us when we arrived, and the flat was everything that we expected. Great kitchen with all the utensils you need, fast internet and comfortable beds. The apartment is in a fantastic location near several tram and underground stations, and it was easy to get anywhere in Vienna. Gary also left a useful guide to Vienna, with maps and instructions to all the important areas. When I next come to Vienna I will definitely get in contact with Gary; couldn't recommend his hospitality more!
