We stayed for three nights. Took a cab from Berlin airport to hotel. Check in was quite ok, but we were the only ones though.
The room is rather spacious for two. There is a boiler, and fridge. No iron, there is a common ironing area at the basement. We requested for extra towels, we were asked to get the extras from the reception. Not an issue. As others have mentioned, the bathroom may be an issue to travellers who are not too close to each other. Not sure if all rooms have the same layout though. The room was a little too dim for our liking. Room service was good and prompt.
Convenient and walking distance to the train station, many eateries nearby. The cafe was also nice. We kept wanting to try but did not have the chance to. It’s closed on Sundays, may wish to take note. More
