Last months we spent a few days in Berlin when Wills parents were here to visit us.
Berlin in Summer is really something else. The city is buzzing and the day doesn't seem to have enough hours to do all the things you want to do (or eat) :) We stayed in Mitte which made it very easy for us as to get around and also to check out all the great places we were surrounded by.
One day we took a bus to the Bauhaus Archive museum which is located close to the Tiergarten.
