Sebastian was a very welcoming and knowledgable host! He waited at the apartment to meet us, gave us lots of helpful advice on places to visit, eat and party, and left us a print out of his tips too! He's a very laid back guy and willing to help with anything you need. The apartment itself was AMAZING. Traditional building with huge rooms and very high ceilings, decorated beautifully with art pieces, lights, antique furniture, thousands of books in German and English....and a massive disco ball in the front room - incredible. We had the best weekend and we very much hope Sebastian will have us back again very soon! :-)
