In a nutshell: this is the worst Airbnb experience I had so far and I'm amazed how many good reviews has this listing.

In some cases this place even dangerous for life and definitely is not children-friendly (there are some electic wires and parts of electric devices which are not covered and can be touched accidentally).

I want to be objective, that's why I'll start my review from pros:

+ Location is great. The very center of Berlin, few minutes from main transport stations.
+ Cheap, really cheap in comparison with other apartments in this area.
+ The host was responsive and quick almost all the time.

Cons:

- The mirror in the bathroom is broken, which is sort of dangerous if you travel with children (as we do).

- There are some electric wires which just "look at you" from walls. Also some devices have uncovered electric parts, which is extremely dangerous for children. We had to switch off some devices or "block" path to them, to prevent our children from possible damage situations.

- Apartments are dirty. Me and my wife we are sort of amazed that there are only 1-2 reviewers who mentioned this. I can imagine that we were the "lucky" ones, who used apartments in not clean condition because of some host' problems (e.g. not enough time to prepeare apartments for us).

Dishes on the kitched are not clean at all. The plastic place where dishes should stay after washing is not clean too, that means, that even after washing dishes, you have to wash them again, before the next use.

There were dust+dirt inside of electric-sockets and near to some kitchen devices. Even the washing machine in the bathroom had dirt+dust on it.

- Toilet doesn't work properly, really =) I'm amazed that I've found the only one review about this thing, but this is "must have" thing for good apartments. In a nutshell: in 50% of cases water won't start to going and you have to push a bit the water tank.

- Some kitchen devices didn't work and the washing machine in the batchroom didn't have few buttons and was dirty too =)

- Some devices which are mentioned on the page don't exist in real life. There were no TV and iron.

To conclude: I definitely won't recommend this place to anybody with children. Also I wouldn't recommend this place to people who care about clean and safe apartments (because this one is definitely not clean and safe).
