Simply amazing apartment. Location is a bit far from the general touristy sites, but the Berlin Wall memorial right outside is stunning. While I didn't really interact with the host, she lived upstairs, and there was never any hesitation to ask a question. The apartment itself is very hip, filled with pop art, and just all around very cozy. There's a coffee maker as well as tea - she even left a couple of haribos when I checked in.
When I come back, I would be thrilled if I could book her place again.
