The apartment description was accurate & we enjoyed our stay very much. On the third floor (with a lift), it was clean, well equipped, spacious, comfortable, great decor and the bedrooms & bathrooms were excellent. On one side of the apartment there's a graveyard, so it's nice and quiet there. Whilst on the other side there is a busy road, which means sleeping with windows open was a little noisy for me, but with windows (double glass) closed it was fine.
While the location of the apartment is not perfect (The restaurants & bars near the river are 15-20mins walk), it is still in a good location and very close (2mins walk) to the subway (Hermannplatz station). The apartment is organised by the company 'Berlin Style Apartments' who were both professional and prompt with their responses.
Overall, the apartment was excellent and I would definitely recommend it. Thank you!
