Alex's apartment on Schillerstrasse is very comfortable. The Charlottenburg area is charming, and the apartment is very close to the Willmersdorfer pedestrian mall, that has a wide range of serves. The transit is so convenient, with a bus to Tegel Airport or the Charlottenburg S-bahn right outside the door of the building. We especially liked the balcony, that has a nice urban vibe. As a host, Alex was helpful in his communication. He responded to requests promptly, and went above and beyond for us several times.
