Karsten was very efficient and very welcoming. A brief tour of the apartment and how everything works plus some very useful tips on the local neighbourhood which turned out to be ideal for my needs. 5 minutes walk to the subway and small local shops and less than 1 minute to a fabulous local German bar and restaurant. Beer and wine in the kitchen [small donation required] plus coffee and tea. A really fabulous apartment in a good neighbourhood and i will definitely be back!
