The home was perfect.
Very very very clean and bright; it is lovely. Maybe the only "bad" thing is the bathroom that is very small, but if u just need for a place to stay during the night to visit and travel Berlin it is perfect.
Also the place where the home is situated is great. It is full of nice bar and pubs and there is also a nice bakery.
It is very easy to reach the home from the subway station and it is only 30-35 mins far from Schönefeld Airport (just changing one bus and subway).
We haven't met Julia but we kept in touch all the time for any suggestion or problem. She was very kind and fast to reply.
We would really thank Julia for anything. :)
