I am trying to plan a winter vacation with my elderly parents, and I need help deciding on the best location. My father has trouble walking, so wondering where folks feel is a nice part of the city and close to X-mas markets and other popular tourist sites? Thanks!
The Hackeschermarkt area is on the major e-w local train line and just across the river from the Museum Island (Museuminsel). Google's AI says there are 80 Christmas Markets in the Berlin area so you can probably find one or more of interest anywhere. But...the Gendarmenmarkt is just west (6-8 blocks) of the Museum Island.
Hackesher Markt is a good area with public transportation nearby and numerous restaurants.
I've stayed at the Adina Hotel at Hackescher Markt a couple of times. Others on this forum have as well.
Each room has a small kitchen and some even have washers and dryers in the room.
