Loved my stay where I've discovered 25h brand. Really cool concept, and I will surely try the other ones in the network.
As for this particular hotel - staff was nice, the bar was great on Friday and Saturday evening, the rooms are cool, my favorite was the rooftop sauna. Wish it opened in the morning rather than only in the afternoon, at least on weekends.
Special mention to the little gifts i found in my shoe the morning after Saint Nicholas :)
The neighborhood is really bad, but luckily the hotel is super close to the train station, in a street that is relatively much better (and smaller) than the other problematic streets. And to be fair, all those "locals" are harmless.
