Betty & Stefan's place is lovely, its in an excellent location very close to the metro (U) which makes it very easy to get around. Stefan always responded to me straight away and gave me good instructions to arrive from the airport, so easy! The studio was the perfect size for a solo traveller and nice and warm on the cold Berlin nights I experienced. It had well stocked cooking facilities and its only a 10 min walk to a great organic (Bio) market. I would highly recommend this place.
