We stayed here for a month and loved it! It is bigger than we expected and was bright. The windows are facing a wall so there isn't any view but they do still bring in alot of light. You can hear your neighbors because of the echo off the wall but that just makes it feel more like a community. You are right next to the Johnstraße Metro stop making it easy to get to anywhere you want to go.
Our only quam was the location of the kitchen sink. Since we were here a month, we were doing a lot of dishes. It's just tucked back in the corner making it a little inconvenient but that isn't really a big deal. We definitely recommend this place!
