Nikolai's apartment is very nice and has the perfect location for exploring Berlin. Supermarkets, tramstops and many restaurants are within walking distance. I particularly like the neighbourhood Nikolai's flat is located in, Friedrichshain park is just around the corner and also Mauerpark and Kastanienallee are very closeby. The apartment is spacious and clean and everything you need is there. Nikolai is a great, easygoing host, very helpful and kind! I really enjoyed my time here and would definitely recommend this place!
