I've stayed in Katharina's house for 2 nights and the overall experience has been fantastic. That was the first time for me using AirBnb and I can say I haven't been disappointed at all. She is the cutest host ever, very helpful and made me feel comfortable as soon as I walked in her house! This is awesome.. It's located in a quiet street at 5 minutes walking from the station. If you love that kind of retro and wooden stuff that's the place for you (Communal areas might be a bit messy because she has a little kid but everything is so so so clean)! The room is big and the bed it's extremely comfortable. They have a cat too, it's so cute and I checked out a bit later because she slept on my lap for 2 hours and didn't want me to leave haha!
