Choose the BWV. You can easily walk to the DHS from the BWV in 10-15 minutes depending on the location of your room. It's quite a bit further (more than twice as far) from the BCV.
Check out this old (but still valid) post by Caskbill:

Unfortunately, the photos are no longer available, but the descriptions are all still valid.
