I provide one bedroom of my 3 room apartment ( 70 square meters + two balconies). We would share the living room, kitchen, bathroom and toilette.
My apartment is decorated in a mix of old and new. It is not cluttered, rather clear and reduced , but still comfortable and cosy (see pictures) .
It's my home and not a hotel room, so treat it like your own home!
Keep it clean! When you move out, return my flat at same condition as when you began your stay, otherwise I will keep 100€ as a cleaning fee from your caution!!!
