Charly is a great host, kind and helpful in preparing a trip to her flat, inculding very very fast answers to messages. The accomodation is in a great place, close to 3 U-Bahn lines and via those to Alexanderplatz. The house is calm and silent, a great base for everyone who wishes to stroll around Berlin all day, and then arrive to a comfortable place where one can rest after a huge day of adventures.
