Perfect place to stay while visiting Berlin. The place itself is bright, spacious, very nicely designed and has all the amenities you need. Also has perfect views of the Berlin skyline.
Location is great too, just around the corner from a nice canal with lots of bars and restaurants and close to U-bahn for easy access across the city.
It is at the top of a tall building so a fair climb up the stairs but if you don’t have any problems with stairs it’s definitely worth it.
