I had rented Billie & Max's place for my cousin.
The flat looked very clean and matching to the description, great location and a real service door to door to the guest.
Despite a little key confusion at the start, Billie has been quickly reactive and very professional with us, with a great communication between her and the guest.
I wasn't "on the spot", but regarding to what my cousin said and the contact I had with the host, I would definitively recommend staying at Billie & Max's place!
