Most berlin accessibility info online is outdated. Here's what works from someone using wheelchair daily.

Brandenburg gate area fully accessible with smooth pavement, ramps. Museum island hit/miss — Pergamon has good elevator but neues museum elevator breaks constantly. Fernsehturm accessible entry but viewing platform gets crowded, hard to navigate.

Public transport better than most cities but still frustrating. Newer u-bahn stations have elevators, older don't. Bvg app shows accessibility but not always accurate. S-bahn generally more accessible than u-bahn. Restaurants in mitte/prenzlauer berg tend better but always call ahead.
