Anna was always very prompt in replying to our enquiries and we thoroughly enjoyed our 5 night stay in the apartment which was very quiet. All the beds including the sofa bed were very comfortable. All the furnishings and equipment were new and clean. The apartment is in a delightfully elegant Viennese building with both a lovely staircase and a lift! The location is brilliant and the apartment is in easy walking distance of many of the main sights of the city. It is also close to the underground and trams. Four of us lived there very comfortably.
