Positives: Great location, really love this part of Berlin and nice area for co-working which was really useful. It's very modern and trendy. Really easy to get here from BER airport too.
Negatives: The bed wasn't that comfy for us which was quite surprising given the place felt very modern. The other thing we struggled with a little was that the room was really stuffy but if we kept the window open the tram stop is directly outside and is very noisy. I wouldn't want to stay here in the summer months due to this.
