I stayed at Ariane's place for 5 days and found the experience pleasant. The apartment is in a great location, minutes away from Hackescher Markt and Alexanderplatz. The apartment looked as we'd expected it and was clean and tidy. I would really recommend a stay at Ariane's as it is situated in a location which is a fantastic base to explore Berlin. Communication with Ariane and Serpil was good and they responded speedily to our emails and texts. Would 100% recommend to others.
