Anna's place was excellent for my one-week stay. She was a great communicator and she even took phone calls from my airline when they left my luggage in Berlin.
The bathroom could have been a little cleaner (I had to clean the bottom of the bathtub before I could use it) and I had to get my own toiletries. Otherwise, there were no issues. I recommend staying because of the space, convenience, and great host for such a good price.
