Thanks to Ralph and this nice flat in Kreuzberg. Ralph pointed out some great areas to visit both around the flat and across the river. We explored and had a great time. The flat is located in a vibrant area, close to awesome shops and restaurants. And it is well communicated, so you can visit the rest of Berlin too. The flat is enormous and provided a good space for our small group. There is not too much furniture or decor; the flat is simple and excellent for a comfortable stay. :) And great value for money- this is a honest and kind price for smaller budget travellers.
