Staying at Rita's was a great experience! The room was just as described - clean and bright! Her apartment is very well located. I never needed to take public transportation to get where I wanted to go, but I did notice that there are several bus/U-bahn stops nearby. Rita is very friendly! I didn't get the chance to talk to much with her, but I know that if I had had any trouble, she would have been willing to help me! I'd definitely recommend staying with Rita if you are traveling to Berlin.
