You definitely want to stay at Janet's place, it has everything you need to make you feel like home in Berlin. The apartment has great style, the bathroom and kitchen were very clean and organized, the bed was amazing. It's exactly what you see in the pictures. Also, the neighborhood is beautiful. The apartment is just a few blocks away from great spots in Berlin.
Janet couldn't be present during my stay, but she was super kind and attentive by message before and during my stay. I would definitely recommend this place to my friends and family.
