I stayed at Janina' s for about 4 months and I had a fantastic stay! She is a very friendly, easy-going and kind person. Every problem or doubts I had, she was there to help me:)
The neighborhood feels safe and the house is very connected to public transportation: there are bus stops just outside the door and also tube station is about 7 mins walking:)
My room was spacious, bright and clean. I have no hesitation in recommending this place:)
