This place was great for my 2-night stay in Vienna. I was staying here alone but felt very safe in the building and the surrounding neighborhood. The location was a quick 10-minute walk to the Old Town. The apartment was clean, well furnished, and stylish. With the windows open the street was a little noisy at times at night, but that's expected in any big city.
The check-in process was also very easy as one of the hosts met me and showed me around the apartment. The wi-fi is actually a hotspot that you can take out with you during the day, so that was very convenient for me as I would have had to pay for data roaming otherwise. I would stay at one of Eva & Friends's places if I'm ever in Vienna again and would recommend to a friend!
