We were 3 children and 2 adults. Friends. There are so many restaurants shops and things to see near to the flat. Everyone was really friendly and communication in English was never an issue. The flat is on a really cool street. Although we occasionally heard people outside it was very quiet. There is the underground and trams very close. An all day ticket which you can use on all transport was just over 7euros. The East side gallery which is a stretch of the wall is walking distance from this flat. Walking towards the wall detour to the back of revaler street. Lots of cool clubs there. All in all we had a brilliant time in Berlin. Saw everything we wanted too and enjoyed our stay at the flat
