A lot of the kerbs were not level with the roads so a bit of a bump

Dropped kerbs at most crossings , obviously heritage building materials like cobbles make things difficult. Travelling by public transport wasnt particularly viable the gap between train and platform plus stairs between lines

Couldn't go into Checkpoint Charlie museum and some other attractions

we have had challenges by the ubahn with lifts out of order and BVG with system out of order. By railroad the challenges was to find a train with ramp. We were late one evening but by help of Bundespolizei they managed to get a train with a ramp so we could get home. We experience almost all the berliners as very helpful
