Excellent location, 3 minute walk away from the metro that can take you directly into the heart of Vienna (Volkstheater, Stephensplatz). Nearby is a really cool jazz club called the Blue Tomato--highly recommend checking it out!
The place is spacious and perfect for two couples or solo travelers. The two bedrooms are comfortable and bathroom is clean with great shower. No AC but the host was kind enough to provide fans for us.
