Good location, low value for money.
I stayed at this place with my child and his mother for one month. While the location was superb, the place itself had a lot of flaws; space is much more reduced than what is showed in the photos, the shower was basically a single stream, water service would stop functioning multiple times throughout the week, neighbors are noisy from Friday to Sunday, etc.
German is a very polite host but the stay is definitely overpriced for a mid-term stay (you can find much better in the same neighborhood for the same price) I would not recommend it for more than a night or two and definitely not for a family. If you are a group of friends or a young couple, you might definitely enjoy the great location.
