A great flat in a great location, walking distance from Alexanderplatz and Brandenburg Thor, and within 2 minutes from SpittelMarkt, U2 station. Communication with Zana was excellent, and he gave me early checkin and late checkout free of charge. There was an issue with wifi, and he let me know about the problem one week prior, however I decided to stay and am glad made this decision. A wonderful place to visit and see Berlin from.
