Inside a classic building, the flat has a modern decor just like all the photos shown. It is spacious, bright, and clean. The beds and pillows were comfortable and were like in hotel quality. Although we experienced some malfunction of the heater at our first night, the hosts were super responsive and showed willingness to follow up. They also made local recommendations, which made our trip, first time in Vienna, much unforgettable and smooth. Definitely will stay in this place again!
