David was friendly and flexible.
The appartment is really nice, very sunny and it has good energy. Everything functions properly, it seems it has just been refurbished. The location in Prenzlauer Berg is also perfect.
The only negative is the bed. It is not a double bed, but two single beds and so you tend to fall in the gap in the middle if you like the person you are sharing the bed with ;-) A double duvet would also be welcome.
