The environment in the museum is really good and very comfortable.
1 It is not recommended to follow a group. Switzerland has very good tourism resources. Almost every scenic spot has its own tourist information center. Usually there is definitely a train station, where you can get all useful tourist information for free, including the latest train and bus timetables, which is very suitable for self-help tourism.
I heard about this museum for the first time, so many communication tools
Berne Communication Museum A place worth visiting
It’s not fun to travel abroad with a group tour
