Checkin/out was very easy.
The appartment is well heated which is welcome with Berlin winter. Clean.
Bed in living room is a bit hard. The bedroom ones are very comfy. There is a coffee table and a desk in the bedroom so we were able to have nice separate spaces with my friend.
Kitchen equipment is ok. Frying pans could be changed.
Transportation works well, bus stops a couple of blocks away. Nice coffee/bakeries nearby.
