My boyfriend and i stayed at Serda's apartment for four days and we really enjoyed. The apartment is perfectly located in Friedrichschein, very close to many restaurants, bars and pubs; it is also very close to public transports and we managed to visit Berlin very easily. The room was clean and very big, it had everything we needed. Serda has been very kind giving us some advice about restaurants and communication was perfect. Absolutely recommended for a perfect stay in Berlin!
