Excellent and very good value. Sonia was very hospitable without being intrusive, her apartment was spotlessly clean and tidy, and very comfortable. She provided extra touches, like a supplies of tea and coffee, also a first aid kit and even travel adaptors. Her apartment is on the top floor and there no lift, but she very clear about this on the website. There were nearly very good transport links, the only downside being it quite a walk to the nearest S Bahn; the trams were much closer but less frequent, especially later in the evening, and as I was visiting in December it could be a bit chilly waiting outdoors! Good use of the BVG app could minimise this though, it very helpful. Overall would highly recommend.
