Wow, what great experience. From communication, to check in, to location, to the space itself, the flat was wonderful, as was our stay in Vienna. My wife and I plus our two young adult daughters. Everyone had their own space, and it was clean, modern and not cluttered. Conveniently located within walking distance of EVERYTHING, and if by chance not, Karlspaltz subway station less than one block away! Highly recommend this space for families who want to be together vs. separate hotel rooms. Full kitchen, washer, heated towel racks, etc. A very nice space and a very nice stay indeed )and the local schnitzel is not too bad either) !!
