We had a great stay in the Skygallery. Everything was perfect and in line with the AirBnB description. We liked in particular the space (3 bedrooms, outdoor terrace, big living room and kitchen space, 2 well equipped bathrooms), the decoration (brand new, great harmony of colors and materials, some personal touch as well), the equipment (complete, modern, well functioning) and the location (close to the Rathaus where there was an outdoor Film Festival). Constantin (and his family) is a great his, always responsive and very welcoming! We would definitely go there again next time in Vienna!
