We had an absolutely wonderful visit in Gregors unbelievable apartment. Besides the fact that it is in the historical Stefan Zweig building, the location was perfect for us, never mind the fact that the unbelievable view of the city from on high was spectacular. The apartment was wonderful and clean. The kitchen had everything we needed, the bed was nice and big, the place had its unique Viennese charm with beautiful old wooden floors and a fantastic mega-sized old window, a giant bathtub that my daughter liked to play in, and everything we would need. Yes, it is quite a trek of stairs to get up there, but completely worth it just for the amazing view. Gregor was a very helpful and wonderful host. The communication was just right, and we really had a wonderful time going down to the Christmas market at the RatHaus, which was just down the street and easily accessible via strassenbahn. It was simple to get everywhere, we even took the bus to get back to the train station, as well as used the bus to go to the Main Shopping St., Maria Hilfer strasse. I only wish that we had more time.. I would highly recommend this building to anyone wanting a spectacular view of Vienna, in a charming Viennese apartment, in a really wonderful part of town that is easily accessible. We will definitely try to stay here again when we come back to Vienna. Thank you Gregor!
