The apartment was beautiful and very clean! The location was perfect for walking to Innerstadt and all the sights within, as well as spots in surrounding neighborhoods. The aesthetic of the apartment was really nice; we loved how spacious it was and the amenities available, such as an ironing board, coffee, etc. However, we were unable to sleep at night each night because of the heat. We wish the hosts had kept fans in the apartment because the heat was unbearable. When we contacted Cristoph he recommended keeping the windows open at night- which we had been doing- but that didn't help one bit; with the windows open the noise from the street was so loud throughout the night it made it impossible to sleep (we were close to the city center so late night partiers and early morning construction). We asked Cristoph if he had extra fans but he didn't. If he did that would have made us much more comfortable and happy. Lack of sleep really impacted our stay in the apartment and quality of our whole trip in Vienna. In addition, there weren't enough towels provided for the 4 of us. When we asked for extras Christoph was very helpful and prompt with his reply- his cleaning crew brought us plenty more! I do want to reiterate it was a very nice place to stay and would recommend. Just make sure you ask for fans in advance if it is hot!
