The flat was quite spacious and amazingly clean. It's located right in the middle of a very lively part of Friedrichshain with a bunch of cafes and restaurants around. With public transport, you can get to the city center in ~30min, which is great too. The flat is equipped with a number of amenities and utensils of decent quality. The host made my self-check-in easy by providing codes for the main building entrance and the flat door. Thus, it was impossible to lose my key during the stay, which was quite handy.
I'd love to stay here again!
