Location

At the same time, you benefit from the short distance to the city and a very well-developed infrastructure: various shopping facilities, kindergartens, and schools up to secondary level are available in the municipality.
The location is also attractive in terms of transport: the motorway access and the Basel city center can be reached in about 10 minutes by car, and the next public transport station is about 5 minutes' walk away.
