Nicolas is incredible. He was very accommodating and very quick to respond with any questions. He is also flexible with check-in and check-out time, which was extremely helpful. The place was very clean and had all of the necessities for a few night stay. The neighborhood outside the apartment had a lot of life within walking distances. However, it was very quiet when you were in there. The apartment was walking distance to some tourist attractions, and it was close to many metros to get you to the ones further away. This is definitely the perfect place to stay in Vienna.
