Berlin : Day 1

We are 10 people from Meetup for a 5 days trip in Berlin. We left East Midlands last night. We are in different acomodations but 4 of us are staying in the same B & B. The reception closes at 10 and as we had let them know that we were to be there rather around 11 they agreed to leave the keys by the building door. We couldn't find them so we asked at the café next door. There, very kindly, they reached the landlady on the phone. She came round to open the door and to give us the keys of our bedrooms. Mine is about 25 sq m and has 7 beds ! In fact during the university year it's a residence for students as well.
