The apartment is stunning and Géraldine is a great host. I stayed there with friends for a couple of days and Géraldine is super nice and made us feel very welcome during our stay.
The apartment has a large living and dining area to socialize in after a long day out in Berlin. Check-in/Out was a breeze, as all communication with Géraldine.
I would definitively stay there again if I had the opportunity!
