First of all:
I prefer short-notice bookings.
Requests 1-2 weeks before arrival are perfect.
Longer plans in advance are sometimes a bit difficult for me.
But please just try!
My flat is in the middle of West-Berlin, directly in the mostly gay and very safe area of Nollendorfplatz-"Kiez" with a lot of good restaurants, outdoor cafés, small shops, famous store KaDeWe and Gedaechtniskirche and a beautiful fruitmarket on weekends.
