There is not much to say except that everything was perfect !!
The location, the check in, the cleanliness, and the punctuality. From the apartment you can really get to so many central points of Berlin even by foot.
Also, I thank Toni, a really super host, for offering me her keychain with Berlin written on it which I really fell in love with since day 1 of my staying.
Again thank you very much and really recommended !
