Exciting news... we found a house! We found a house that is a lot bigger than our current apt, and cheaper as well. It's only about 10km (a little over 6 miles) from the kids' school. The local train takes only 15 minutes to get to Basel (with its international airport and further train connections) and runs every 30 minutes.
We're really excited about it! It has a bedroom or each of the kids and we have a big bedroom. And although our bedroom is unfinished, we get to finish it out however we want to (within reason) at the owner's expense. It's set in the quaint German village of Wintersweiler (Efringen-Kirchen).
