My girlfriend and I stayed at Nina's palce for four days and it was a really pleasant experience. The apartment was bright and you could see the breathtaking sunsets from the window as it is on the top floor. It was easy to find as the location is central and surrounded by many shops and food places. Nina was an amazing host providing us with local tips and communicating really fast and comprehensive. I would rate the stay 5/5 and would definitely come back if I had to look for a place to stay in Berlin.
