Hanna's place was clean, homely, and lovely. It's located in a quiet neighbourhood, and is also close to the U-Hahn station and Mariahilfer shopping street. Going to the inner city of Vienna is about a 20 minute walk from the place. We had a bit of trouble opening the front door because we arrived late and Hannah had to leave the keys at a local pub nearby, but all you need to do is turn the key counterclockwise hard (harder than what most North American keys would feel like). Hannah was kind and gracious to give us a personal and very informative tour around the inner city with her baby daughter, and also a few tips for exploring the city. The place itself is fairly big, very clean, and well maintained. Overall, I would definitely recommend Hannah's place to anyone visiting Vienna!
