Apartment may seem to be far from the main activities, but it's only a 20 minutes ride on a metro, and metro station is just 5 minutes by foot. On the other hand, it's well connected for a car drive and easy to get to the autobahn.
Not sure how about summer, but in winter we could always find a parking place on the street, there were a couple big heaters and warm blankets in the apartment. Kitchen has everything that is needed.
If you like quite neighborhoods Sahba apartment is a good pick.
