Completely sufficient for one night and a visit to the technology museum.

Arrived last night. There were enough parking spaces for the night, free. Got pizza around the corner. Slept well. The next day we walked to Lidl for fresh sandwiches. Then into the museum. Nice museum. Walked around for 6 hours.

It is a fenced parking lot, where it is not clear whether you are allowed to stand overnight or not. It's a shame, otherwise we would have liked to have stayed and looked at the museum the next day
