We had a wonderful stay at this charming apartment, which was housed in a gorgeous 19th century building, belonging to a Baroness at one point in time (a resident told us the history of it). The apartment was beautiful, excellently organised (fully-stocked kitchen), clean, roomy and we couldn't have asked for a better place to stay in Vienna. It is across from the Burggarten, which made this a prime location. A short walk, and you're in Neubau and the Museum Quartiers or near Stephenplatz. Perfect location.
Uliana and her colleagues were efficient and kind. We would highly recommend this place - it's ideal for a couple and a small child.
