The apartment is nice and clean, close to everything you need. That being said, it's pretty much a hotel. It's a giant building full of airBnB's with personnel and a registration desk. Don't expect any close and personal experience here. Also right now this place is still an active building site. Locals are being pushed out of the cities to build places like this and they don't like them at all. Not an authentic Berlin experience..
but it is clean, comfy, well-equipped and well-located for sure.
