Though there is a small number of visitors parking spaces, using public transport is definitely the smarter option in Berlin. Just watch out to go to the right Berliner Straße, there are a couple streets with the same name.
Heads up, you have many options! The U7, 101, 104 or 249 all go to Blissestraße. From there it’ll take you 4 more minutes by foot until you reach our office. You could also take the U3, U7, 101 and 115 to Fehrbelliner Platz and walk 6 more minutes to our office. Or hop on the 115 to Mansfelder Straße/Barstraße and then 4 more minutes by foot.
