Martin's flat is far and away the best experience I have had on Airbnb. He was friendly, quick to respond, and offered many local tips. Check in and out was a breeze. The space itself was hip, clean, and well supplied for any stay, including a fully stocked kitchen. The neighborhood was quiet and leafy, but still full of places to go and things to do, and was only a five minute walk from the nearest U-bahn. 110% recommend.
