The room is really nice. Nice decoration. Confortable comferter. Wifi access. Welcoming pack. Private Kettle.
Nevertheless it is quite expensive for Berlin. It is about the same as a good hotel. Not much difference, apart from the fact that you can cook in a mini-place.
I do not recommend it if you want to live the Berlin experience, live and talk with Berliners. In Studio A, you do not have access to the flat. There is a specific entrance for 2 rooms that are Air Bnb rented. It is more a business than a human intercultural experience. And that's ok. Just be aware of it. Cheers.
