You have audioguides in all languages!! Its very very good

It is free of charge.

Around it - yes. But in some places the stones are too close to each other and the road can be tight.

Si, un ora basta. È all spero. .non ci sono audio guide

Oui, il y a possibilité de se garer à proximité notamment vers la Posdammer platz ou bien dans les rues à côté ou vers le Tier garten. En fait , il n'est pas très difficile de stationner sur Berlin.

Yes that would be about right... Bon voyage

It is a good question. I definitely agree that the audio guide would not be appropriate. Personally, I found this museum to be very moving, but I don’t recall there to be many graphic pictures of dead bodies etc. I would focus less on the enormity of the tragedy and instead look at the individual stories of those who perished. There is one room which details letters sent by those who later died and that would be something a 12 year old would be able to comprehend. To conclude, I would only take a mature 12 year old child here.

In the first row this is not a museum, it's only monument of granite gray blocks near by Brandenburg tor. If you like to know more about this, you should visit a museum which is on the left side of monument, below the road. Pls, check only what is an appropriate ege to enter in this museum. I did not visit it because there was a long queue.

Está al aire libre y no necesitas guía. Puedes visitarlo a la hora que quieras.

No, but better to go early and have the place to yourself
