Julian gave me the entire apartment to me for my race weekend in Berlin. He has considered all minor details even with where are the local spots for food. Staying in his apartment let me feel I am not a tourist, but a "temporary" local resident, which is what I really want. Tidy, clean, well organized, stable wifi, loaded pantry and mini-bar (though I didn't use), it even has a washer for laundry. The location is perfect, right on the edge of Tiergarten, easy access to S/U Bahn, and Julian even loaned his bicycles to me. It is just a wonderful place to stay.
