Edda is a very awesome host!
Unfortunately I didn't meet her in person but she gave me a cool and very helpful advices for my stay in Berlin.
She has been care about my stay sending some messages asking how is it going, lovely!
I met her housemate Alans and she was really really kind!
The room is very big and the entire house is comfortable with a nice balcony.
There are some good restaurants, coffe bars nearby and the the house is close to the U2 metro.
You must stay in Edda's house during your visit in Berlin!
