We very much enjoyed our short stay here. Florian allowed us to leave our bags in the apartment prior to check-in, which was a lifesaver. The apartment was very quiet for our whole stay. The bed platform was a little wobbly, so don't plan on doing any acrobatics, but it is plenty stable for sleeping. The four stories of stairs weren't a huge problem for us, but if you do have a lot of luggage it could become quite tiresome. The apartment is located about 25 minutes walk from the train station and maybe 20 minutes from the main city. We didn't mind this walking at all as it gave us an opportunity to see the city. The apartment was clean, but there was a very strong smell. It was almost like a very odorous cleaner or spray had been used throughout the entire apartment, and the smell gave me a headache for he first few hours of being there. The towels were also very "crunchy", maybe just from being air-dried after washing? But this was a little off-putting. Aside from these minor things, the apartment is very unique and we would consider staying again on another trip to Vienna.
