I enjoyed staying at this apartment. It's well situated: in front of the tram stop, and 5 mins to the main train station. The InnBerlin , who were in charge of welcoming us, were very nice and helpful. The place was very clean and looked exactly as it shows on the pictures. Nevertheless, 2 things annoyed me: there was not enough toilet paper (one half-used roll for 2 people for 5 days). Second point: the smell of cigarettes in the corridors and the apartment. It seems that even though it's forbidden to smoke in the building, neighbours don't really care. The smell was very strong, outside and inside the apartment, which gave me a headache during the w end.
