Johann and Gitti's home is comfortable. We were in Vienna in a very hot period (35C) and but the the home remained very cool and pleasant - there was certainly no need for the air conditioning. The patio onto the large back garden is a delightful place to take your meals. Public transport into the city and sights is really good and only a short walk away and it is really only a pleasant stroll to the vineyards on the edge of the city. We very much enjoyed our stay.
