This flat was charming and wonderful! Super cosy, super cute, and very accessible by tram to the centre of the city (takes about 40-45 minutes). Communication with Boris was extremely easy, check-in was super smooth, and the flat itself is wonderfully comfortable and nicely decorated. I had some small cleanliness issues with the flat (seemed tidied rather than fully cleaned), but I'm confident that with feedback Boris will address this in future! Had an awesome stay in Vienna.
